Higher neural functions This article explores higher neural functioning. Anatomy of the cortical and association areas Cerebral Cortex Primary motor Primary sensory Association areas: Account for ~80% of cortical surface Association Areas Structurally identified from primary sensorimotor areas due to o Granular appearance o Presence of all 6 cortical layers Other regions are named according to function Unimodal (one specific function): e.g. Brodmann areas 18 & 19 form part of visual association cortex Multimodal (more than one function or modality): e.g. Limbic area = Acquisition, discrimination, Major multimodal association areas o Parieto-occipital-temporal association area

Unformatted text preview: Comprises anterior-temporal & post-parietal areas o Limbic association area o Pre-frontal association area o Delineations are not exclusive & overlap between areas is seen Other association areas named according to function Mainly unimodal & closely related topographically to associated primary region o Visual association cortex: Areas surrounding primary visual cortices, areas 18 & 19 o Auditory association cortex: Brodmann area 22 Damage to association cortices results in some interesting psychological disorders, inc. Various aphasias, agnosias & apraxias Disconnection syndromes characterised by o Loss of certain faculties &/or o Replacement with an inappropriate faculty...
