The Brainstem
• Brain’s basement – oldest
and innermost region.
• Begins where the spinal
cord enters the skull and
swells slightly, forming
the medulla.
• Brainstem is the point at
which nerves to and from
each side of the brain
connect with the body’s
opposite side.

The Medulla
• Controls the heartbeat
and breathing.
• Destroyed medulla =
instant death

Pons
• Sends signals
between the
cerebrum and the
cerebellum.
• Plays a role in
sleep and in
relaying sensory
information (sight,
taste, touch,
sound, smell)
Reticular Formation
•
•
•
Takes some information from the
spinal cord and sends it to the
brain.
Also plays a critical role in arousal.
“The reticular formation has also
been traced as one of the sources
for the introversion and
extroversion character traits.
Introverted people have been
found to have a more easily
stimulated reticular formation,
resulting in a diminished desire to
seek out stimulus. Extroverted
people, however, have a less
easily stimulated reticular
formation, resulting in the need for
more stimulation to maintain brain
activity” Wikipedia

Cerebellum
• Means “little brain”.
• Responsible for some
types of nonverbal
learning and memory.
• The most important
function is
coordinating voluntary
movement.
