How to get the best current activity state in continuous attractor network with population decoding?

Models of head direction and place cells often use some form of attractor network (Redish, Elga et al. 1996; Zhang 1996; Samsonovich and McNaughton 1997; Stringer, Rolls et al. 2002; Stringer, Trappenberg et al. 2002). Typically an array of cells …

Understanding Cognition in the Human Brain Project

Imagine an apple — its greenness, sour taste and its fresh, crisp crunch; how does the brain create a representation of such an apple?

This is one of the questions the Human Brain Project (HBP) is asking. To better understand …
