cerebrum Flashcards
what is contained in the cerebrum?
cerebral cortex
hippocampus
basal ganglia
olfactory bulb
what is a lobe?
functional areas within brain
what are gyri?
ridges between lobes
what are sulci?
grooves between gyri to increase SA of cortex
what are fissures?
long narrow splittings (eg the longitudinal fissure splitting two hemispheres of brain)
what is grey matter?
located on the outer layer, grey due to neuronal bodies
what is white matter?
inner layer and is white due to myelinated axons
function of frontal lobe
movement
speech
personality
decision making
critical thinking
short term mem
function of parietal lobe
sensation
perception
proprioception
language
function of temporal lobe
hearing
language
memory
function of occipital lobe
vision
perception
primary motor area
FL
motor output
sends signals out to muscles
premotor area
FL
higher order planning of movement before its sent to primary motor area
supplementary motor area
FL
postural motor map
bilateral coordination (coordinate limbs)
prefrontal cortex
FL
cognition
behaviour
personality
dm
impulse control
frontal eye field
FL
voluntary eye movement
conjugate gaze
saccadic movement (shifting gaze)
Broca’s area
FL
speech production
links to Wernicke’s area
primary somatosensory cortex
PL
receive and process sensory input
sensory association area
PL
complex multisensory processing (eg weight, temp, texture)
auditory cortex
TL
processing auditory info
audiotry association area
TL
complex processing of auditory info
Wernicke’s area
TL
comprehension of written and spoken language
directly connects to Broca’s area
fusiform face area
TL
facial recognition
visual cortex
OL
receive and integrates visual info
visual association area
OL
complex processing of what and where
