Synaptic Darwinism and neocortical function

Implications of synaptic digitisation and error for neocortical function

Recent work in hippocampus suggests that correlation-based synaptic strengthening occurs both imprecisely and digitally. We explore this in a model in which synapses are created according to a "tness function and are occasionally incorrectly placed. Synapses spread beyond the high "tness (w . ) area to lower "tness (w 1 ) areas to an extent that depends on the error rate and the "tness ratio w ...

Neocortical Function in Behavior

:1' : . , ,_ The impOrtant role of neocortical mechanisms in cognitive behavior has ! \. been a focus of scientific interest for the past century and a half. In the early 1800's, arguments raged between physiologists (e.g., Flourens [14]) and phrenologists, many of whom were good anatomists (e.g., Gall and Spurzheim [6]), as to whether the cerebral mantle functioned as a unit or whether a mosai...

compactifications and function spaces on weighted semigruops

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
