Old Brain

New Brain

Cerebral Cortex“New Brain” (Higher level cognitive processes)

Frontal lobe - Front – Speech, emotion, memory, motor

Parietal lobe - Top – Sensory input (skin, etc.) Temporal lobe - Side – Auditory processing Occipital lobe - Back – Vision processing

Cerebral Cortex Lobes

Cerebellum (not part of Cerebral Cortex)

Central Core“Old Brain/Animal Brain”(Basic functions) Cerebellum - Coordination, sensory analysis, (involved

with problem solving) Spinal Cord - Communication between brain and body Reticular Formation - Sleep, arousal, and attention Hypothalamus - Regulates temperature, hunger, thirst, Pons - Sleep and arousal Corpus Callosum - Connects the two hemispheres Thalamus - Relay center – coordinates incoming &

outgoing Medulla - Regulates unconscious functions
