What are rostral, caudal, dorsal, ventral, medial and lateral?
Name the two types of photoreceptors.
What are rods and cones?
Name the pathway of auditory information processing.
What is spiral ganglion neurons → nuclei in the medulla → inferior colliculus → thalamus → cortex?
Name the area at which odorants are absorbed
What is the mucus layer?
Name the 3 sectional cuts of the brain. (Draw this out)
What are coronal, sagittal, and horizontal plane?
Name the characteristics of rods and cones.
What are [rods: functions in low lights, no color detection, low spatial acuity] and [cones: functions in high light levels, color detection, high spatial acuity]?
Name the brain region that had tonotopic organization
What is the primary auditory cortex?
Name Wilder Penfield's major finding (there are two but think about the most relevant one) (hint: stimulation)
What is stimulation to one side of the brain would lead to a response on the opposite side of the body?
Name the main responsibilities of the four brain lobes.
What is...
Occipital Lobe (vision), Temporal lobe (sensory processing), Parietal lobe (w/ PFC to make decisions and receive sensory info), and Frontal lobe (judgment and motor control)?

Name the two responsibilities of the brainstem.
What are controls automatic functions (e.g., sleeping, breathing) and makes modulatory neurotransmitters (DA, 5-HT, NE)?
Name the two important structures in the inner ear.
What are the cochlea and basilar membrane?
Name the neurotransmitter that's released onto muscle fibers.
What is acetylcholine?
Name the main responsibilities of the thalamus and hypothalamus
