How Neurons Communicate…
IPSP = Inhibitory Postsynaptic Potential
EPSP = Inhibitory Postsynaptic Potential
Important for sleep, mood,
learning; HIGH = Schizophrenia;

The Brain =
Many Neurons
Glial Cells
The Brainstem
• The Medulla Oblongata and
the Pons controls breathing,
heart rate, digestion
• The Cerebellum controls
coordination of movement
and balance (Karate; Dance.

The Midbrain
• The Midbrain receives,
integrates, and projects
sensory information to the
forebrain
*
– Thalamus
• conducts information to
specific areas of cerebrum
Hypothalamus
– _____________
• produces hormones and
regulates body temperature,
hunger, thirst, sexual
response, circadian rhythms
*
• Cerebrum
– with cortex and
corpus callosum
• higher thinking
