A dendritic disinhibitory circuit mechanism for pathway
... read the word. One possible solution to this task is for a decisionmaking area to locally open its gate for the deliberate pathway (colour-naming) while closing its gate for the more automatic pathway (word-reading). Using computational models, we propose that the dendritic disinhibitory circuit can ...
