What is the function of the cerebellum?
Coordination of muscle tone and movements, equilibrium, and balance.
What are the two types of aphasia caused by damage to Broca’s and Wernicke’s areas?
Broca’s Aphasia (Expressive Aphasia) and Wernicke’s Aphasia (Receptive Aphasia).
Which lobe of the brain is responsible for visual processing?
Occipital lobe.
What is the function of the hypothalamus?
Controls the autonomic nervous system, thirst, hunger, and body temperature regulation.
What connects the cerebral cortex with lower CNS parts?
