Important Parts of Brain
Thalamus (sensory
hub)– message is sent from retina to
optic nerve to thalamus – to the
occipital lobe of the brain.
Hypothalamus – is
our motivation center (hunger, thirst and
sexual motivations)
Hippocampus - Memory
Amygdala - related to emotion
(fear and agression)
Cerebellum - motor
movements
Medulla - Heart beat and
breathing
Reticular Formation - ArousalAlpha
Brain waves:
More Apha = resting
Less alpha = more thinking/processing
information
Homunculus
– imaginary little man that
maps out locations of the origin of
sensations and motor movements in the
cerebral cortex. His feet are in
the middle (the fissure) of the brain and
his arms and head extended to the outer
edge of the brain (laterally)
