BA # and anatomic location
which BA # represents the precentral gyrus
BA 4
BA 9, 10, 11 correspond to the prefrontal region or the
cognitive association cortex
a person will present with expressive language deficits if they have damage to which BA #
44, 45
association areas function
control our ability to understand sensory information and coordinate a reponse
2 sensory areas + functions
primary somatosensory cortex: allows conscious awareness of sensation and the ability to localize it
somatosensory association area: understanding what is being felt
which BA #s correspond to the postcentral gyrus
3, 1, 2
the somatosensory association cortex is represented by
BA 5,7
what will happen if there is damage to primary visual cortex
functional blindness (no conscious awareness of sight)
2 types of association areas and function
primary: tied to sensory modality
heteromodal: integrates a bunch of senses together
2 occipital areas + functions
primary visual cortex: handles contralateral info from retina, only handles awareness of what we see
visual association area: processes stimulus features such as form, color, and motion
angular gyrus is represented by BA #
39
BA 41 is known anatomically as Heschl's gyrus and functionally known as
primary auditory cortex
effects from lesion to the parietal lobe
neglect: not responding to meaningful information presented to the side of the opposite brain lesion
functions of parietal association areas
sensory guidance of motor behavior and spatial awareness
2 auditory areas + functions
primary auditory area: processes raw sounds
auditory association area: complex auditory processing
BA 41 represents the anatomical location of
Heschl's gyrus
the parietal lobe contains the primary sensory cortex and is represented by BA
1,2,3
damage to parietal association areas include
impairment of body awareness, motor control and visual guidance of motor behavior
function of temporal associations areas
recognition of sensory stimuli and storage of factual knowledge (vision, touch, hearing)
BA #s for olfactory areas and what they are specialized for
BA 34 encoding memories based on smell
the cognitive association cortex is in which region of the frontal lobe
prefrontal
BA 18,19 anatomical area and function
anatomical area: pericalcarine cortical area
function: visual association cortex
individuals with temporal lobe damage can present with what disorders
agnosia, visual agnosia, prosopagnosia
function of frontal association areas
organizing behavior and working
4 motor areas + functions
primary motor area: precise, conscious or voluntary movement of skeletal muscles
premotor cortex: complex movements associated with highly processed sensory info, planning movements
frontal eye fields: voluntary movements of eyes
broca's area: word articulation (movements necessary for speech)
