Functional localization of Telencephalon Flashcards
How many layers of the cerebrum is there
6 layers
What layers are thicker in the heterotypic cerebral cortex (+ what are they called)
If 2+4 are thicker it will be called granular cortex (usually found in sensory localizations)
If 3+5 are thicker it will be called agranular cortex (usually found in motor regions)
Area 4 (primary motor area) - in, out, function
in- VLTN + premotor area
out- Corticospinal to lamina 7,8,9, corticobulbar to CNs
Function- Voluntary motor control of CL neck upper limb, trunk, LL, muscles of head
Area 6 (Premotor area)- in, out, function
In- Ventral ant + Ventral lat thalamic nuc
Out- Area 4
function- generates programs for motor routines
Area 8 (frontal eye field)- in, out, function
In- Visual cortex (calcaline cortex)
out- Corticomesenphalic axons to CN 3,4,6
Function- mvmt of eyes
Area 44/45 (brocas)- in, out, function
In- Wenickes area
out- corticobulbar to CN x
Function- involved in expressive speech
Area 9/10/11/12 (prefrontal cortex)- in, out, function
In- many areas
out- premotor/primary motor cortex
Function- high mental function (judgement/foresight)
Area 1/2/3 (primary somatosensory)- In, out, function
In- Ventral post lat and ventral post medial
Out- frontal lobe and lamina 2 via corticospinal/bulbar
Function- Skin sensation CL body
Area 5/7 function
Allows you to identity object you are touching without visual aid
Area 43 function
taste sensation projects here
Area 39/40 (extended wernickes area) function
understanding of written language (in dominant cortex)
Area 17 (primary visual area)- in, out, function
In- Lat geniculate body optic radiations
Out- frontal lobe
function- visual perception
Area 41/42(Primary auditory cortex)- in out, function
In- info from med geniculate body
out- wernickers area
Function- sounds perception
Area 22 (wernickers) function and out
out- to frontal lobe and brocas area
function- understanding spoken language
Area 18/19 (visual association cortex)- function
understanding what u are seeing
