Self-Organization of Neural Systems – An Evolutionary and Developmental Perspective
Understanding self-organization of biological nervous systems is key to understanding cognition. This talk presents our recent research efforts on understanding neural self-organization from the evolutionary and developmental point of view. A computational model is built up for co-evolving the development of the neural system and body plan of an animat based on primitive organisms such as hydra and flatworm. The neural and morphological development is simulated with a multi-cellular system governed by a gene regulatory network. Our results suggest that energy efficiency might be the most important constraint in neural self-organization. In addition, a close coupling between the evolution of the neural system and body plan is revealed.
A framework for modelling activity-dependent neural plasticity is briefly discussed in the second part of the talk, where the BCM plasticity rule is regulated by a gene regulatory network. The gene regulated BCM rule is adopted for training spiking neural networks. We demonstrate how activity-dependent neural plasticity can improve the network’s ability for spatiotemporal pattern recognition.
