|
connect gyri in the same hemisphere.
|
|
|
Describe Commissural tracts?
|
connect areas in opposite hemispheres.
|
|
|
Describe projection tracts?
|
Connect the cerebrum to other brain regions.
|
|
|
Describe the shape and location of the limbic system?
|

|
|
|
Major motor regions of the cerebral cortex include?
|
Primary motor area, broca's area.
|
|
|
Why does the terms left brain and right brain exist?
|
Because of the functional asymmetry between the two hemispheres.
|
|
|
What does the thalamus do?
|
Relays almost all sensory input to the cerebral cortex.

|
|
What is the reticular formation?
|
collection of small nuclei in the brain stem. they act together to help maintain consciousness and to regulate muscle tone.
|
|
|
The cerebellum does what?
|
coordinated movements, and provides constant feedback to motor areas.
