local of higher brain function Flashcards
how many broaden areas
52
explain broaden areas (general decsription
using a microscope, noticed patterns of nerve cells in brain (same areas have same patterns in every brain)
noticed that the cell type and thickness differed in diff parts
conclusion- structure must be related to function
what was the conclusion of broadmens
structure must be related to function
what is layer 1 of the cortical lamination and explain its connection
neurophil (cortico-cortical)
neurophil (cortico-cortical)
which layer
1
what is layer 2 of the cortical lamination and explain its connection
small pyramidal neurons (cortico-cortical)
small pyramidal neurons (cortico-cortical)
which layer
2
what is layer 3 of the cortical lamination and explain its connection
small pyramidal nueorns (interhemispheric)
small pyramidal nueorns (interhemispheric)
which layert
layer 3
what is layer 4 of the cortical lamination and explain its connection
stellate neurons that have locally ramifying axons
stellate neurons that have locally ramifying axons
which layer
4
which layer of cortical lamination has major thalamic inputs
4
what is layer 5 of the cortical lamination and explain its connection
larger pyramidal neurons that cause outputs for leaving cortex (ie going to subcortical structures)
larger pyramidal neurons that cause outputs for leaving cortex (ie going to subcortical structures)
which layer
5
what is layer 6 of the cortical lamination and explain its connection
some pyramidal neurons and other neurons that leave the cortex
some pyramidal neurons and other neurons that leave the cortex
which layer
6
association area allow simple or complex brain function and explain
complex
process sensory information from primary cortices
what are some examples of complex brain functions done by assocaition cortices
ability to have thoughts and feelings (emotions)
awareness of physical and social circumstances
use language to express thoguhts
store and access info (memory)
sleep and wake
true or false: we have many primary areas but few assocaition areas
false
know general areas of the primary cortices
motor = precentral
somato = post central
visual=occipital (calc)
auditory = sup temporal
gusta= insula
olf = pirifirom
(hypothalamus, thalamus and brainstem as well)
what are the 3 association cortices
partietal
temporal
frontal
what is the general function of the parietal association cortex
mediates attention
what is the general function of the temproal association cortex
identification of stimuli
what is the general function of the frontal association cortex
planning, decision making
