Localisation and Lateralisation Flashcards
what is localisation of function
the principle that specific abilities/functions are within/have specific areas in the brain
where are the motor areas found
in the motor cortex
where is the motor cortex
in the frontal lobe along the precentral gyrus
what does the motor area control
voluntary movements, with different parts of it controlling different parts of the body
where are the somatosensory areas found
in the somatosensory cortex
where is the somatosensory cortex
in the parietal lobe along the postcentral gyrus
what does the somatosensory area do
uses sensory information from the skin to produce sensations of touch, pressure, pain and temperature which it then localises to specific body areas
where are the visual areas found
in the visual cortex
where is the visual cortex
in the occipital lobe
what does the visual area do
information from the retina is transmitted along the optic nerve to the brain via the thalamus where visual information is produced
where are the auditory areas found
in the auditory cortex
where is the auditory cortex
in the temporal lobe
what does the auditory area do
processes auditory information, recognising it to result in an appropriate response
what does the auditory area work
sound waves are converted to nerve impulses in the cochlea (inner ear) which travels via the auditory nerve to the auditory cortex via the brain stem and the thalamus
what happens along the brain stem
decoding takes place
