Document Summary

Hemianop(s)ia - blindness in one side of visual field. V1 up: higher-order disorders of construction, space, and meaning. Inability to identify objects in motion, very rare. Loss of ability to detect color on only one side. Pinna - flaps on ears catch sound waves and funnel them to external auditory canal. Ear drum - vibrates when sound waves hit it. The nerve with many names in charge of hearing and vestibular sense. Sound entering each ear is processed by both the ipsilateral and contralateral hemisphere. A1, or heschl"s gyrus/i, or brodmann"s 41 and 42, or transverse temporal gyri. Superior temporal sulcus (sts) between superior and middle temporal gyri. Five main types of connections: hierarchical sensory pathway, dorsal auditory pathway, polymodal pathway, medial temporal pathway, frontal lobe projection. Connections of the temporal cortex: hierarchical sensory pathway. From primary and secondary auditory and visual cortical regions lateral temporal cortex terminate in temporal pole (ba 38) Auditory travels through superior temporal gyrus (stg)
