Basic CNS Pharmacology & CNS Stimulants Flashcards
Which part of the brain functions in sensations, perception, voluntary movement, learning, speech, and cognition?
Cerebral cortex - processes and interprets information
Which part of the brain functions in respiration, cardiac and vasomotor control, and reticular formation?
Medulla of the hindbrain
Which part of the brain functions in voluntary movement in space and time, controls balance and eye movements, as well as repetitive cognitive functions?
Cerebellum
Which part of the brain acts as a relay center and filters and modulates sensory information transmission to the cerebral cortex?
Thalamus
Which part of the brain controls the ANS, hormonal regulation, internal homeostasis, and emotions?
Hypothalamus
