Call for abstracts (Closed)

The study of nonlinear aspects of neural dynamics increased significantly in recent years. The accessibility of new experimental tools that provide high spatial and temporal resolution recordings of neural function at cellular, circuit and macro level generated a huge amount of new data, which need the application of nonlinear analysis methods. New nonlinear computational models (e.g., pulse-coupled neural networks, spiking neuron models, large scale multi-component statistical simulation models, neuropercolation models and others) were developed in recent years that can be employed to analyze, interpret and explain the available data. The goal of this workshop is to create a forum for researchers in this exciting research area, to exchange ideas and to discuss recent developments, and also to outline perspectives for future activities.

 

Examples of topics of interest are listed below: 

·         Experimental aspects of spatio-temporal coding

·         Mechanisms of emergent synchrony in the nervous system

·         Break down of synchronous behavior and its role in cognitive processing

·         Phase transitions and spatio-temporal neurodynamics

·         Role of chaos for robust neural processing in noisy environment

·         Incorporation of neuromodulation into conventional neural models

·         Nonlinear models of neurodynamics based on:

-         Differential equations

-         Coupled map lattices and cellular automata

-         Neuropercolations in random graphs

-         Liquid state machines

·         Spatio-temporal information processing for:

-         Perception

-         Learning, memory, and reasoning

-         Motor control, navigation, and decision making

-         Communication

-     Neurological and psychiatric disorders

 

The workshop will feature invited talks and also contributed talks. Contributions are solicited from CNS'2004 participants interested in biological and/or computational aspects of nonlinear spatio-temporal neural dynamics. The contributions should be in the form of a one page abstract, summarizing the content of the talk. Selected contributions will be allocated a 10 minutes presentation time. Interested authors please contact any of the organizers (peter.andras@ncl.ac.uk, perdi@kzoo.edu, kozma@socrates.berkeley.edu). Deadline for abstracts: June 21, 2004. E-mail notification about acceptance for presentation will be sent out by July 2, 2004.

 

The organizers intend to publish a journal special issue containing the papers related to the talks given at the workshop.
