Document Summary
2nf3: basic and clinical neuroscience march 19th 2018 the temporal lobes. Anatomy of the temporal lobe: anterior to the occipital cortex, tissue below the lateral/sylvain fissure, subcortical temporal lobe structures, limbic cortex, mediating manifestation of feeling, amygdala, connected to sense of emotionality fear, hippocampal formation, memory, spatial navigation. Subdivsions of the temporal cortex: lateral surface, auditory areas, brodmann: 41,42, 22 (b, visual areas (ventral stream) Inferotemporal cortex: von economo: te, brodmann: 20, 21,37, 38 (b, insula (part of temporal cortex) Fissure: contains gustatory cortex (taste processing) and, auditory association cortex, assist with refinement of, multimodal/polymodal cortex auditory message, superior temporal sulcus, categorizing info. Input from auditory, visual, & somatic regions: medial temporal cortex (limbic) Includes planum temporale: provides auditory info, roughly brodmann areas 41, 42, and partially 22 are major processing areas. Hierarchical sensory pathway: principle and area that means the brain will recruit more areas as the places involved with audition become more refined.
