The Brain
The Brainstem
• The Medulla Oblongata and the Pons controls breathing, heart rate, digestion
• The Cerebellum controls coordination of movement and balance (Karate; Dance. Separate Section of the brain)

The Midbrain
• The Midbrain receives, integrates, and projects sensory information to the forebrain
*
– Thalamus• conducts information to
specific areas of cerebrum
– _____________• produces hormones and
regulates body temperature, hunger, thirst, sexual response, circadian rhythms
• Cerebrum– with cortex and
corpus callosum• higher thinking
*
Cerebrum
• Lateralization– Right – Pattern Recognition, Face Recongition, Spatial Relations, Nonverbal thinking– Left – Language, Math, Logical Operations
