The functional dichotomy at the level of subcortex is debatable in terms of cognitive linguistic processes. The current study attempts to resolve these queries through in depth analysis of cognitive linguistic functions by administering CLAP-M on 15 participants with right subcortical lesion and 15 patients with left subcortical lesion. The results evinced significantly poorer performance by participants with right subcortical lesion. This astounding finding can be accredited to the presence of robust contralateral connections of right subcortex to left prefrontal cortex through medial claustrum.
