J.M. Cortes, A. Greve and M.C.W. van Rossum. Dynamical effects on familiarity discrimination. AIP Conference Proceedings 887: 217-223, 2007 [pdf] One process involved in recognition memory is familiarity discrimination. Familiarity distinguishes almost immediately after stimulus presentation whether the item was previously encountered (old) or novel. By using a formalism based on attractor neural networks, we discuss different dynamical processes affecting familiarity discrimination. First, we compare two different familiarity discriminators, the […]

How is brain function influenced and constrained by its underlying structural connectivity? To reply to this question, we derive a new method that provides a new brain atlas that –emerging out of a careful hierarchical clustering analysis– combines both structural and functional data to discover network modules common to both data sets. A region within this atlas is functionally connected and structurally wired (with fibers). To the best of our […]
