localization of function
the research strategy of linking specific structures in the brain
with specific psychological or behavioral functions
>>> localization data
The research endeavor of determining what specific job is
performed by a particular region of the brain.
clinical neuropsychology includes this
motor areas
cerebral cortex: brain tissue for organizing and controlling body
movements
sensory areas
cerebral cortex: brain tissue for organizing and analyzing
information from the senses
association areas
areas of the cerebral cortex that are not involved in primary
motor or sensory functions; rather, they are involved in higher
mental functions such as learning, remembering, thinking, and
speaking
75% of cerebral cortex
,contains many subregions, each specialized for a particular
function
projection areas
regions associated with specific sensory or motor processes
(arrival and departure)
> input and output
projection areas > contralateral control in movement
stimulation to the left hemisphere leading to movements on the
right side of the body, and vice versa.
frontal lobe
planning movement (motor cortex)
executive functions
occipital lobe
visual information processing
parietal lobe
somatosensory cortex (touch/pressure/temperature)
spatial processing attention
temporal lobe
auditory processing
memory
sensory areas
, functional areas of the cerebral cortex that provide for conscious
awareness of sensation (sight, touch, hearing)
sensory maps- assignment of cortical space is governed by
function not anatonomical proportions
>>more important information = more cortex
(sensitive areas have much more space, for example the lips)
areas of the body that are near to one another are
represented by similarly nearby areas in the brain.
contralateral organization (crossing over)
nearby regions are processed by spatially close regions
EX: somatosensory area in L hemisphere receives its main input
from R side of body
> touch and vision info processed from one side of body is
processed in the opposite hemisphere
Visual projection areas contralateral to physical space in visual
field
lateralization
L half of brain controls R side of body, R half of brain controls
L side of body
**Language is mostly in L hemisphere

callosum )
