What is the process of hearing?
Sound waves are converted into vibrations of hair cells, which then activate ion channels responsible for auditory signaling
What are the structures involved in hearing?
Tympanic membrane (eardrum), ossicles, cochlea, oval window, round window
What are the depth cues in vision?
Monocular cues (retinal height and relative size) and binocular cues (retinal disparity)
What is the central vision?
Highly acute, sharp, clear vision in the fovea
What is peripheral vision?
Highly sensitive vision produced by rod photoreceptors in dim conditions
What is the point of fixation in vision?
The area between the eyes where peripheral vision is focused
What are the pathways involved in visual processing?
Magno pathway (motion and depth) and Parvo pathway (color and form)
What is the role of the hypothalamus?
It is responsible for primary drives such as food, sex, and hunger
What is the role of the parietal lobe?
It is responsible for proprioception (spatial processing) and somatosensation
What happens to the brain during REM sleep?
The prefrontal cortex decreases in activity, the amygdala and hippocampus are active
What is the role of the SCN in the hypothalamus?
It regulates the circadian pacemaker and pineal gland activity
What is REM rebound?
The increased amount of REM sleep following a period of insufficient REM sleep
