“Computational modeling of large-scale resting-state activity in fMRI and MEG”

Tristan Nakagawa

Researcher, IFReC

Abstract:

Ongoing spontaneous brain activity patterns raise ever-growing interest
in the neuroscience community. Complex spatiotemporal patterns that
emerge from a structural core and interactions of functional dynamics
have been found to be far from arbitrary in empirical studies. They are
thought to compose the network structure underlying human cognitive ar-
chitecture. We use a biophysically realistic computer model to study key
factors in producing complex spatiotemporal activation patterns. We present
modeling approaches to study decreased physiological signal complexity
in aging and demonstrate that delays shape functional connectivity in an
oscillatory spiking-neuron network model for MEG resting-state data.

About CiNet’s Friday Lunch Seminars:
The Friday Lunch Seminar is CiNet’s main regular meeting series, held every week at 12:15 in the beautiful main lecture theatre on the ground floor at CiNet. The talks are typically 40mins long and orientated towards an inter-disciplinary audience. They are informal, social, and most people bring their own lunch to eat during the talk. They are open to anyone who is feeling curious and wants to come, regardless of where you work.
