Cerebral Hemispheres (stephens) Flashcards
why did we develop a neocortex
encephalization of the sensory and motor systems
develop of language
lateralization (corpus callosum development)
the neocotex is what part of cortex
-how much of cortex does it take up
newest part of cortex, 90%
primary somestetic broadmen
3,1,2
primary auditory broadman
41,42
primary visual broadman

broac’s speech
44,45
wernickes

occipital eye field
17
frontal eye field
8
primary motor
4
premotor
6,8
which layers of cortex are important for roles in higher cognitive fnct such as memory, interpretation of sensory input
I and II
which layers of cerebral cortex receive afferents
and what kind of fibers
III and IV
-mainly corticocortical fibers
what layers are the source of efferents from cortex
V and VI
what interconnects the neocortical areas of the 2 cerebral hemispheres and largest of many is what
commissural fibers
-corpus callosum
