Visual proceesing
What is an EEG, and what is it used for?
Measuring brain conductivity (Action potentials) in the cerebral cortex is used to measure brain cortex function and activity.
Which part of the brainstem contains the Vagus nerve (CN X) and autonomic system control centers
Medulla Oblongata
What are the functions of the ventricular system?
buoyancy, protection, and nutrients to neurons and glial cells
