(form) primary and secondary cortex
(to) lateral temporal cortex
(to) temporal lobes
medial temporal lobes
hippocampus
visual hierarchical pathway (location)
thru inferior temporal gyrus
auditory hierarchical pathway (location)
thru superior temporal gyrus
Dorsal Auditory Pathway
(from) primary and secondary auditory cortical region
(to) lateral temporal cortex
(to) temporal lobe
Hierarchical Sensory Pathway (function)
"What pathway"

orienting, location of sound
Polymodal Pathway (where it is)
(from) auditory and visual hierarchical pathways
(to) superior temporal suclus
Polymodal Pathway (function)
help decide what category a stimulus belongs to
Medial Temporal Pathway
(from) perirhinal cortex (in temporal lobe)
(to) entominal cortex

to help decide or plan what to do
Hemianopia
Blindness in one half of the visual field
Scotoma
Part of visual field missing, blind spot
Akinetopsia
unable to identify objects in motion; both sides V5 are affected; very rare; motion analysis problem
Achromotopsia

primary auditoy cortex (tonotopic) [V1}
tonotopic
pertains to the way in which the primary auditory cortex is ORGANIZED so that neurons that respond to particular frequencies are grouped together

secondary auditory cortex (location&function
around primary auditory cortex; belt & para belt region
