Localisation of cunction Flashcards
define localisation of function
the theory that different areas of the brain are responsible for specific behaviours, processes or activities.
who argued the localisation theory
Brocas and Wernicke
what happens when one part of the brain is damaged in localisation theory
the function associated with that area is also affected.
how many heispheres is the brain divided into
- right and left.
what is lateralisation
when some of our physical and psychological functions are controlled or dominated by a particular hemisphere.
what is the outer layer of the brain called
cerebral cortex.
what are the four lobes of the cerebral cortex
frontal, parietal, occipital and temporal.
where is the motor area
back of the frontal lobe
what dose the motor area do.
controls voluntary movements.
Damage may result in loss of fine motor movements.
where is the somatosensory area and what dose it do
front of the parietal lobes, processes sensory info about skin.
where is the visual area
in the occipital lobe at the back of the brain.
what dose the visual area do
each eye sends info from right visual field to left visual cortex and visa versa.
where is the auditory area and what dose it do
in the temporal lobe.
Analyses speech based information.
what side of the brain is language redistricted to.
left side.
What is Broca area
Broca identified a small area in the left frontal lobe responsible for speech production.
