PREFACE

We at the Aalesund University College (AAUC) are grateful for having the honour of hosting the 27th European Conference on Modelling and Simulation, or ECMS 2013.

Located in the Art Nouveau town of Ålesund, AAUC lies at the heart of the maritime industry cluster on the west coast of Norway. With five faculties and more than 2000 students and 200 staff, the university college offers a wide range of study programmes in engineering, maritime operations, biotechnology, international business, and health science, including a newly accredited master programme in simulation and visualisation. Rooted in our strategy plan is a strong focus on applied maritime technology and operations, which manifests itself through some of the world's most advanced offshore simulators and our close ties to the maritime industry in both training, education, and research. As a result, modelling and simulation permeate almost everything we do at AAUC, from basic engineering courses, through training of offshore personnel, to novel research.

Across all tracks, this year's conference has received excellent contributions from some of the world's most highly regarded researchers in their fields. In particular, with the human brain as a common denominator, keynote speakers Stephen Grossberg and May-Britt Moser present their respective work on grid cells, place cells, and brain maps for space; Peter and Megan Neilson introduce their adaptive model theory and human movement control systems; and Sigal Berman talks about telerobotics and hand gestures for remote control. Having secured these keynote speakers has also spawned the creation of new tracks in robotic applications and computational neuroscience, the latter of which include specially invited talks by Peter Latham and Matteo Marsili.

We are very proud that six brand new tracks are introduced at ECMS 2013, dealing with modelling, simulation and visualisation in training and education; maritime technology and operations; robotic applications; computational neuroscience;

optimization; computer vision; and social interaction. In addition, ten traditional tracks are offered in topics such as agent-based simulation; complex systems; finance, economics and social science; high performance modelling and simulation; industry, business, and services; intelligent systems; logistics, transport, and management;

process control; and policy modelling. In total, some 141 accepted papers and oral talks are presented, with more than 170 participants from all over the world attending the sessions.

For 27 years, ECMS has set the stage for an independent, highly interdisciplinary scientific forum for researchers and practitioners from all over the world to present and discuss the latest findings, challenges, and future directions of their work. We, the organisers of ECMS 2013, hope that the high quality of accepted papers and participants as well as our exciting scientific, social, and cultural programme all ensure the success of this year's conference and we look forward in excitement to which directions the conference will take in the future.

How do grid cells and place cells arise through development and learning? Medial entorhinal grid cells and hippocampal place cells provide neural correlates of spatial representation in the brain. A place cell typically fires whenever an animal is present in one or more spatial regions, or places, of an environment. A grid cell typically fires in multiple spatial regions that form a regular hexagonal grid structure extending throughout the environment. Different grid and place cells prefer spatially offset regions, with their firing fields increasing in size along the dorsoventral axes of the medial entorhinal cortex and hippocampus. The spacing between neighboring fields for a grid cell also increases along the dorsoventral axis.

The GridPlaceMap neural model shows how grid cells and place cells may develop in a hierarchy of self-organizing maps. In this conception, grid cells and place cells are learned spatial categories in these maps. The model responds to realistic rat navigational trajectories by learning grid cells with hexagonal grid firing fields of multiple spatial scales, and place cells with one or more firing fields that match neurophysiological data about these cells and their development in juvenile rats. The place cells represent much larger spaces than the grid cells, which enable them to support navigational behaviors.

Homologous self-organizing map laws for grid cell and place cell learning. The grid cell and place cell self-organizing maps both obey the same laws, and both amplify and learn to categorize the most frequent and energetic co-occurrences of their inputs. The different receptive field properties emerge because they experience different input sources. The place cells learn from the developing grid cells of multiple scales that input to them. The grid cells learn from stripe cells of multiple scales that input to them, each with a different directional selectivity. The name “stripe cell” acknowledges that the spatial firing pattern of each such cell exhibits parallel stripes as the environment is navigated. Burgess and his colleagues introduced an analogous concept of “band cells”, but they are formed by the mechanism of oscillatory interference.

Grid and place cell learning occurs in models that are built up from either rate-based or spiking neurons. The results using spiking neurons build upon a previous rate-based model of grid and place cell learning, and thus illustrate a general method for converting rate-based adaptive neural models into models whose cells obey spiking dynamics. Remarkably, the spiking model continues to exhibit key analog properties of the data. New properties also arise in the spiking model, including the appearance of theta band modulation. The spiking model also opens a path for implementation in brain-emulating nanochips comprised of networks of noisy spiking neurons with multiple-level adaptive weights for controlling autonomous adaptive robots capable of spatial navigation.

Learning the dorsoventral gradient of receptive field sizes and oscillation frequencies. Both the spatial and temporal properties of grid cells vary along the dorsoventral axis of the medial entorhinal cortex. In vitro recordings of medial entorhinal layer II stellate cells have revealed subthreshold membrane potential oscillations (MPOs) whose temporal periods, and time constants of excitatory postsynaptic potentials (EPSPs), both increase along

this axis. Slower (faster) subthreshold MPOs and slower (faster) EPSPs correlate with larger (smaller) grid spacings and field widths. The self-organizing map model simulates how the anatomical gradient of grid spatial scales can be learned by cells that respond more slowly along the gradient to their inputs from stripe cells of multiple scales. The model cells also exhibit MPO frequencies that covary with their response rates, and exhibit some properties of modular organization of the different spatial scales. The gradient in intrinsic rhythmicity is thus not compelling evidence for oscillatory interference as a mechanism of grid cell firing.

Homologous spatial and temporal mechanisms: Neural relativity. This spatial gradient mechanism is homologous to a gradient mechanism for temporal learning in the lateral entorhinal cortex and its hippocampal projections that was proposed in the 1980s.

Such adaptively timed learning has simulated data about the role of hippocampus in supporting learning that bridges temporal gaps, such as occurs during trace conditioning and delayed matching-to-sample. This type of "spectrally timed learning" has Weber Law properties that have been confirmed by recent experiments that have discovered "time cells"

in the hippocampus. Spatial and temporal representations may hereby arise from homologous mechanisms, thereby embodying a mechanistic “neural relativity” that may clarify how episodic memories are learned.

Homologous processing of angular and linear velocity path integration inputs. The inputs that drive the initial development of grid cells and place cells are angular and linear velocity signals that are activated by an animal's navigational movements. The model proposes that both angular and linear velocity signals are processed by ring attractor neural circuits. Angular velocity signals are proposed to be processed by ring attractors that are composed of head direction cells, whereas linear velocity signals are proposed to be processed by ring attractors that are composed of stripe cells. The outputs of head direction cells modulate the linear velocity signals to multiple directionally-selective stripe cell ring attractor circuits. This modulation is sensitive to the cosine of the difference between the current heading direction of movement and the ring attractor’s directional preference. Each stripe cell ring attractor is sensitive to a different direction and spatial scale. Stripe cells are the individual cells within each such ring attractor circuit and are activated at different spatial phases as the activity bump moves across their ring locations. They may be activated periodically as the activity bump moves around the ring attractor more than once in response to the navigational movements of the animal.

The model’s assumption that both head direction cells and stripe cells are computed by ring attractors that drive grid and place cell development is consistent with data showing that adultlike head direction cells already exist in parahippocampal regions of rat pups when they actively move out of their nests for the first time at around two weeks of age.

Stable learning, attention, realignment, and remapping. Place cell selectivity can develop within seconds to minutes, and can remain stable for months. The hippocampus needs additional mechanisms to ensure this long-term stability. This combination of fast learning and stable memory is often called the stability-plasticity dilemma. Self-organizing maps are themselves insufficient to solve the stability-plasticity dilemma in environments whose input patterns are dense and are non-stationary through time, as occurs regularly during real-world navigation. However, self-organizing maps augmented by learned top- down expectations that focus attention upon expected combinations of features can do so.

Adaptive Resonance Theory, or ART, proposes how to dynamically stabilize the learned categorical memories of self-organizing maps. Experimental data about the hippocampus from several labs are compatible with the predicted role of top-down expectations and attentional matching in memory stabilization. These experiments clarify

how cognitive processes like attention may play a role in entorhinal-hippocampal spatial learning and memory stability. The proposed mechanism of top-down attentional matching may also help to clarify data about grid and place cell remapping and alignment of grid orientations.

Beta, gamma, and theta oscillations. Within ART, a sufficiently good match can trigger fast gamma oscillations that enable spike-timing dependent plasticity to occur, whereas a big enough mismatch can trigger slow beta oscillations that do not. Such beta oscillations occur in hippocampus during the learning of novel place cells, and have the properties expected when mismatches occur and receptive field refinements are learned. Beta oscillations also occur at the expected times in visual cortex and in the frontal eye fields during shifts in spatial attention. Thus, the match/mismatch dynamics leading to gamma/beta oscillations seem to occur in multiple brain systems.

The theta rhythm has been associated with properties of spatial navigation, as has firing of entorhinal grid cells. Recent experiments have reduced the theta rhythm by inactivating the medial septum (MS) and demonstrated a correlated reduction in the hexagonal spatial firing patterns of grid cells. These results, along with properties of intrinsic membrane potential oscillations in slice preparations of entorhinal cells, have been proposed to support an oscillatory interference model of grid cells. Our self-organizing map model of grid cells can explain these data without invoking oscillatory interference. In particular, the adverse effects of MS inactivation on grid cells can be understood from how the concomitant reduction in cholinergic inputs may increase conductances of leak potassium and slow and medium after-hyperpolarization channels.

Model parsimony. Our emerging neural theory of spatial and temporal processing in the entorhinal-hippocampal system exhibits a remarkable parsimony and unity in at least three ways: It proposes that similar ring attractor mechanisms compute the linear and angular path integration inputs that drive map learning; that the same self-organizing map mechanisms can learn grid cell and place cell receptive fields, despite their dramatically different appearances; and that that the dorsoventral gradient of multiple scales and modules of spatial learning through the medial entorhinal cortex to hippocampus may use mechanisms that are homologous to mechanisms earlier proposed for temporal learning through the lateral entorhinal cortex to hippocampus ("neural relativity"), as reflected by data about trace conditioning, delayed matching-to-sample, and "time cells". This mechanistic homolog clarifies why both spatial and temporal processing occur in the entorhinal-hippocampal system and why episodic learning may be supported by this system. No less striking is the fact that both grid cells and place cells can develop by detecting, learning, and remembering the most frequent and energetic co-occurrences of their inputs, properly understood. This co- occurrence property is naturally computed in response to data, such as navigational signals, that take on contextual meaning through time.

The

brain controls spatial navigation in mammals by activating functionally specialized cell types in the medial temporal lobe. A key component of the spatial mapping system is the place cell, located in the hippocampus. These cells – discovered by O´Keefe and Dostrovsky in 1971 - are active only when the animal is entering a specific location in the environment. I will describe the discovery of another component of the mammalian spatial mapping system – the grid cell – which we found upstream of the hippocampus, in the medial entorhinal cortex, in 2005. Grid cells are activated whenever an animal enters locations that are distributed in a spatially periodic pattern across the environment. The repeating unit of the grid pattern much is an equilateral triangle. Grid cells are co- localized with head direction cells and border cells, which contain information about the direction in which the animal is moving and the boundaries of the environment. Despite the discovery of several elements of the mammalian spatial map, the interaction between the components is poorly

understood. We addressed this question first by using optogenetics together with

electrophysiologal recordings of cells in the entorhinal cortex. Hippocampal neurons were infected with an adenoassociated virus carrying genes for a peptide tag that can be visualized by fluroescent antibodies as well as the light-sensitive cation channel channelrhodopsin-2 (ChR2). The virus was engineered to enable retrograde transport through axons of cells with projections into the hippocampus. Infected entorhinal cells were detected by local flashes of light. Channelrhodopsin- expressing cells responded with a short and constant latency to the light. All cell types in the entorhinal cortex were found to respond to the light, suggesting that place signals may be generated in the hippocampus by convergence of signals from all these entorhinal cell types. In addition to discussing the transformation of entorhinal to hippocampal spatial signals, I will devote a part of my talk to asking how the grid-cell network is intrinsically organized. To adress this question we used multi-channel recording from a much larger number of cells than recorded ever before in individual animals. Grid cells were found to cluster into a small number of modules with distinct grid scales, grid orientations and grid asymmetries, as well as distinct patterns of temporal organization. The different modules responded independently to changes in the geometry of the environment.

The existence of distinct and independent modules or grid maps makes entorhinal maps different from the many other sensory cortices where functions tend to be more graded and continous. This is in agreement with the suggestion that the grid map is a product of self- organizing network dynamics rather than specificity in the input. Because the crystal-like structure of the grid pattern is generated within the brain, not depending on specific sensory inputs, we are confronted with an unique situation in which we, by trying to understand how the grid pattern is formed, may obtain insights into how patterns are formed in the mammalian cortex.

Adaptive Model Theory: A History

Megan D. Neilson & Peter D. Neilson

Our accompanying presentation overviews the constructs of Adaptive Model Theory, a computational account of human movement control that has evolved over a research lifetime that began in the 1950s. Its origins are in the fascination of two young people with the prospect of applying their training in physics, mathematics, and engineering principles to the modelling of biological systems. Unlike today, it was an era in which such interdisciplinary work was rare and the path to undertaking it was essentially of one’s own making. In this presentation we explore some of the history of that journey. There was the getting of technical jobs in UNSW’s newly established medical school to provide a gateway to the biological world; the finding of labs where “way-out” ideas were tolerated, if not entirely understood; and the support for part-time graduate research. Not to mention the finding of unmeetable mentors accessible only via the literature.

Experimental work began with studies (without benefit of automated A-D conversion) into investigating the human tonic stretch reflex, not during rest as was usually done, but by modelling the input-output characteristics during voluntary contraction. From these followed a string of experimental investigations to investigate movement disorders, cerebral palsy in particular, but also Parkinson’s disease, stroke, cerebellar disorder, and stuttering. At the time the latter was still widely believed to be psychological in origin. The voluntary movement tracking experiments carried out to model the input-output characteristics of the auditory- motor loop in stuttering and non-stuttering subjects gave strong credence to the now-accepted neurological basis of the disorder. Likewise, following on from the studies of reflexes in cerebral palsied subjects, experimental use of tracking paradigms to separate voluntary and involuntary activity in the purposive movements of this group showed a clear result which is now well accepted clinically. Quite apart from unwanted reflex activity, cerebral palsied subjects lack the ability to generate appropriate movements for a voluntary task, despite a cognitive understanding of what is required. In each of the neurological disorders we studied the experimental evidence pointed to deficits in the formation, maintenance and/or selection of the adaptive sensory-motor models underlying the forward control of voluntary movement.

Hence enter Adaptive Model Theory and the quest for a more general understanding of how the brain achieves control of the inherently nonlinear, nonstationary, uncertain, redundant, unstable system that implements human movement. In parallel with the theoretical

development came more experiment, now mostly with normal subjects. This included examination of control-display compatibility in tracking, acquisition of tracking skill with practice, tracking with differing degrees of freedom, tracking with unusual systems that variously involved gain change, cross-coupling and instability, as well as investigations of predictability in tracking and the response planning strategies that apply. And of course there were the simulations that necessarily accompany the experimental findings and so guide the theoretical evolution. This ultimately has encompassed an account of motor development from the foetus to the mature system. So where now? It’s a long way today from recognising that we can learn about biological systems by modelling their inputs and outputs. A great deal has been done, and not least in understanding the principles of sensory-motor control.

But it’s far from done yet. The mathematics of Riemannian geometry currently offers a new window into the planning of responses of complex systems. Therein lies a future

understanding of human movement and its disorders.
