functions of the olfactory, optic, vestibulocochlear and vagus nerve?
olfactory= sense of smell
optic= vision
vestibulocochlear= hearing and balance
vagus nerve= supplies all important organs like heart
What are the four types of waves?
alpha waves
beta waves
theta waves
delta waves (high amplitude, slow waves)
What is electroencephalogram?
wave patterns
What is aphasia?

parietal lobe (general sensory some vision),
cerebellum (motor skills)
thalamus (gets messages from the spinal cord)
the hypothalamus (regulates the endocrine system)
gratification centers help us feel happy,
aversion centers (feel sad)
What types of cells are present in the cerebral
cortex?
stellate cell (no axons)

What is
meningitis?
