Most experimental studies of decision-making have specifically examined situations in
which a single correct answer exists (externally guided decision-making). Along with such …

Linking microcircuit dysfunction to cognitive impairment: effects of disinhibition associated with schizophrenia in a cortical working memory model

JD Murray, A Anticevic, M Gancsos, M Ichinose… - Cerebral …, 2014 - academic.oup.com
