cerebrum--intensive

Question 1

gray matter Cerebral cortex:

association area types (2)

Answer 1

• unimodal: integrate one specific type of info

- multimodal: integrate information from multiple different sources

Question 2

Basal Nuclei

Answer 2

• gray matter
• clusters of neuron cell bodies found deep within each cerebral hemisphere
• 3 parts:
  
  1. caudate nuclei
  2. putamen
  3. globus pallidus

-fxn: control of skeletal muscle movement

Question 3

cerebrum-white matter

Answer 3

• myelinated axons
• 3 types (also 3 different pathways for action potentials)
  
  1. commissural fibers: connect right and left hemispheres; corpus callosum is the largest
  2. projection fibers: connect cerebral cortex of one hemisphere with other areas of the same hemisphere, and other parts of brain and spinal cord.
  3. association fibers: restricted to one hemisphere, connect gray matter of cortical gyri w/ one another

Question 4

limbic system: structures

Answer 4

• a functional brain system
• 3 parts
  
  1. limbic lobe–structural, 2 main gyri: cingulate gyrus and parahippocampal gyrus
  2. hippocampus: involved in memory and learning
  3. amygdala: behavior, expression of emotion, especially fear
• found only in mammalian brains
• fxn: memory, learning, emotion, and behavior
• only mammals can do the limbo (?)
• when you behave well, you get to learn the limbo, memorize it, and feel good about it!

Question 5

functional brain system

Answer 5

-groups of gray matter that share the same function and the white matter that connects them.
