Lecture 3

Question 1

cortex layers, 1-6

Answer 1

1- no cell bodies
2- cell bodies packed
3- small cell bodies scattered
4- four parts
5- large cells, scattered, big dendrites
6- large cells, closely packed

Question 2

t or f, relative widths of cortex layers changes abruptly from one area to another

Answer 2

true

Question 3

broadmann maps

Answer 3

based off layers of cortex, patterning continues even on inside, differences in layering corresponds to differences in function

Question 4

back part of brain v frontal v premotor v prefrontal

Answer 4

back part of brain- sensory information
frontal- intention
premotor- planning before moving
prefrontal- intention on a larger timescale

Question 5

basal ganglia

Answer 5

structures deep in front half of brain, involved in patterned actions (like movement)

Question 6

limbic system

Answer 6

back half of brain, involved in dealing with un-patterned actions (like monitoring the objective and emotional parts of an experience)

Question 7

sensory information flow

Answer 7

thalamus to primary sensory cortex to secondary sensory cortex to multimodal sensory cortex to either frontal cortex/ hippocampus/ amygdala/ or motor/premotor and then back up again
