Brain Organization and Networking (Week 2) Flashcards
front of the brain
anterior
back of the brain
posterior
top of brain
dorsal
bottom of brain
ventral
side/outside of brain
lateral
middle/inside of brain
medial
4 lobes of the brain
frontal, parietal, occipital, temporal
frontal lobe function
decision making, planning, motor control, high level thinking
parietal lobe function
touch, spatial transformation of spaces, spatial recognition)
what separates the frontal and parietal lobe
central sulcus
temporal lobe function
hearing, higher level vision
occipital lobe function
vision
brainstem components
midbrain, pons and medulla
cerebellum
“little brain”
*has as many cells as in the cerebral cortex
which sensory pathway does NOT go through the thalamus
sense of smell
sensory pathway: eye
light -> retina -> thalamus (LGN) -> primary visual cortex (V1) in posterior occipital lobe
sensory pathway: ear
inner ear -> processing in brainstem -> MGN -> primary auditory cortex (A1)
sensory pathway: skin
touch receptors in skin -> processing in brain stem -> thalamus -> primary somatosensory cortex (S1)
which sensory pathway goes straight to thalamus (no brainstem processing step)
eye
first order thalamic areas
thalamic areas that receives major input from sensory periphery
brodmann’s areas
regions of the cerebral cortex that are defined by their cellular structure and organization
brodmann’s area 17
primary visual area
hierarchical organization of cerebral cortex
primary sensory areas, secondary sensory areas, higher-order areas
what kind of info processed in lower level areas in cerebral cortex
simple sensory aspects (ex. vertical vs horizontal line orientation)
