To deepen our understanding of the complex systems that we study, we need to formulate quantitative and qualitative models and explore those models via computer simulation. At the IAS, SbS brings together researchers who work on such simulation based approaches.

Simulating large-scale brain networks and their inner workings


Computational models of large-scale brain networks have been traditionally focused on reproducing brain dynamics such as resting state activity. However, embedding the mechanisms and structure needed to reproduce brain functions related to perception and cognition, in a way that also matches the neuroanatomical and electrophysiological evidence, has been more challenging. In this talk, I will present two recent examples of computational models of brain networks which include rudimentary but behaviorally relevant functions. The first example will focus on how the delay activity underlying working memory may emerge as a distributed phenomenon across multiple regions of the macaque and human brains –rather than restricted to prefrontal areas as assumed in classical computational models. In the second example, I will present simulations of the mouse brain which show that the integration of signals from multiple sensory sources occurs across multiple brain areas in a context-dependent way. These computational results, strongly constrained by anatomical and electrophysiological data, suggest that both working memory and multisensory integration are intrinsically distributed phenomena in the brain.
