what is a suclcus
and major sulci
furrow, valley
central, pareital-occipital, lateral
what is a gurus
and major gyri
hill
pre-central gyrus, post-central gyrus
what is a fissure
and major fissue
a big sulcus (furrow valley)
transverse fissue
4 lobes and functions
frontal- motor
parietal- sensory
occipital- vision
temporal- memory and hearing
motor cortex of frontal lobe
pre=motor: planning of movement
primary motor: execution of movement
prefrontal cortex
WHO WE ARE
decision making
anticipating consquences
emotion higher cognitive
major division of the brain
cerebrum: cerebral cortex, corpus callosum
diencephalon: thalamus, hypothalamus
brainstem: midbrain, pons, medulla oblongata
cerebellum
internal structures of the brain
cerebral cortex (gray matter) white matter (3 types) deep nuclei
3 types of white matter
commissural tracts e.g corpus callosum
projection tracts e.g corticospinal tract
association tracts e.g communicate motor and premotor
function of primary motor cortex
sending motor neuron to command somatic efferent contraction of muscle cells eg
Function of parietal lobe
somatosensory sensory association information
e.g neurons in a row synapses
specific regions receive sensory from specific regions
intergrating cerebellum role
–coordinates movement guided by sensory feedback
copy of instructions
compares to copy of motor output
adjusts motor output for coordination
role of basal ganglia
select appropriate movement for given situation
initiate movement
terminate movement
