A spiking model of cortical broadcast and competition (Shanahan 2008)

Accession: 116871

"This paper presents a computer model of cortical broadcast and competition based on spiking neurons and inspired by the hypothesis of a global neuronal workspace underlying conscious information processing in the human brain. In the model, the hypothesised workspace is realised by a collection of recurrently interconnected regions capable of sustaining and disseminating a reverberating spatial pattern of activation. ..."

Usage:
At the matlab prompt type GWTrials to start the top-level program.
This will run for a little under 4 hours generating figures in 13
training with several trials per session.  These figures are similar
to those in figures 7, 8, and 9 in the paper:



The code contains some corrections, so doesn't reproduce the exact 
figures from the paper, although they are qualitatively the same.
