Vision/Miscellaneous
Name the six directional terms used to describe the location of brain regions (draw out on whiteboard)
What are rostral, caudal, dorsal, ventral, medial, and lateral?
True or false: When hair cells are depolarized they trigger an action potential
What is false?
Name the cells in the olfactory pathway that fire action potentials
What are olfactory receptor neurons?
Name the brain region responsible for organizing movement and sending commands
What is primary motor cortex?
Name the three sectional cuts of the brain (draw out on whiteboard)
What are coronal, sagittal, and horizontal plane?
Describe the mechanism by which hair cells are depolarized
What are movement of stereocilia open mechanically gated potassium channels leading to K+ rushing into cell?
Name what binds to the GPCRs of cilia
What are odorants?
Name the region in which death of neurons leads to the motor symptoms of Parkinson’s disease
What is the substantia nigra?
Name the cell in the visual pathway that fires action potentials.
What are retinal ganglion cells?
Name on what end of the cochlea a high-frequency soundwave can be found
What is the base (closer to the start of the inner ear)?
Name what area in the brain olfactory information goes to after reaching the olfactory bulb
What is the olfactory tract?
Name the brain region containing the “map of the body” and why might some regions be overrepresented?
What is the primary motor cortex and body parts with careful motor control are overrepresented (ex. hands and face)?
Name what the visual pathway is called BEFORE it passes through the optic chiasm
What is the optic nerve?
Name the pathway of auditory information processing
What is spiral ganglion neurons → nuclei in the medulla → inferior colliculus → thalamus → cortex?
Name what would occur if you were to damage the piriform cortex
What is you would not be able to perceive smell at all?
Name the neurotransmitter that is released into muscle fibers
What is acetylcholine?
Name the reason why glutamate has an inhibitory effect on bipolar cells
What are they have metabotropic glutamate receptors?
Name the brain region that has tonotopic organization
What is the primary auditory cortex?
DAILY DOUBLE: Name what brain region you would have to damage to prevent the conscious perception of smell but not the emotional perception
What is the thalamus?
Describe the role of dopamine in movement
What is used to communicate with the basal ganglia (responsible for controlling movement)?
