Our seminars consist of two half-hour sessions with two different speakers (to keep it lively and ensure a broad appeal). The speakers for this first seminar will be:

Petra Vertes (Brain Mapping Unit)
Generative models of brain functional networks: Brain functional networks derived from fMRI data are increasingly being used to understand the flow of information within both healthy and anomalous human brains, during tasks as well as in the resting state. While a sophisticated set of network measures is now available to describe the topology of brain networks and how it is altered in these different scenarios, the driving forces that shape the networks into these characteristic topologies remain unknown. Here we consider simple generative models for the probability of functional connection (an edge) between two cortical areas (nodes) separated by some Euclidean distance in anatomical space.

 

Murray Shanahan (Computing, Imperial College London)
Knotty-Centredness: finding the connective core of a complex network: This talk will describe a measure called knotty-centredness that attempts to capture the extent to which a network possesses a densely intra-connected and topologically central core. Some applications to brain networks will be presented, including a newly constructed connectome of the pigeon forebrain.
