What is the limbic system?

It includes parts of the cerebral cortex, thalamus, and hypothalamus.

It recognizes social cues such as facial expressions, elicit emotions, and memory.

What is reticular formation?

It is responsible for limiting and filtering sensory information from reaching conscious mind.

What are the 2 hemispheres in the cerebellum connected by?

Vermis

What is the name of the white matter in the cerebellum?

Arbor vitae

What is the function of the cerebellum?

It controls proprioception and balance

What is the function of the Medulla Oblongata?
