Document Summary
I(cid:374)ferior fro(cid:374)tal g(cid:455)rus (cid:894)bro(cid:272)a"s area(cid:895: prefrontal cortex, area of the frontal lobe that receives input from the dorsomedial nucleus of the thalamus, receives significant input from the mesolimbic dopamine cells in the tegmentum. Sts, and visual regions of inferotemporal cortex, and from subcortical amygdala. Links with emotional behaviour: anterior cingulate cortex, bidirectional connections with motor, premotor, prefrontal cortex, and insula. Functions of the prefrontal cortex: controls cognitive processes so that appropriate movements are selected at the correct time. Internal cues: temporal memory (working memory): memory for what has just happened role of. Impairment in autonoetic awareness = deficit in behavioural self-regulation: medial or ventral frontal injury = loss of self-knowledge and struggles in daily life. Impairment in use of verbs and correct grammar: agrammatism: damage to the supplementary motor cortex, mute forever if bilateral, but only few weeks if unilateral, visual search task. Left orbitofrontal lesion but sometimes follows right orbitofrontal damage: decreased design fluency due to right orbitofrontal lesion.
