Abstract

It is now known that the striatum plays a role in engaging attentional resources and linguistic rule computation while also serving phonological short-term memory capabilities. The ventral semantic and the dorsal phonological stream dichotomy assumed for spoken language processing also seems to play a role in cortico-striatal perception. Based on recent studies that correlate deep Broca-striatal pathways with complex syntax performance, we use a previously developed computational model of frontal-striatal syntax circuits and hypothesize that different parallel cortico-striatal language pathways are processing may contribute to canonical and non-canonical sentence comprehension separately. We will modify and further analyze a thematic role assignment task and corresponding reservoir computing model of language circuits and will examine the models performance under various parameter regimes.
