Afferent and Efferent -> define
There's a dragon in all of our brains because we have a brainstem

The brain stem is the main brain of a fish, amphibian, or reptile.
Little evidence that these structures provide these animals with conscious control of their
behavior.
-
-
It has centers for coordinating movement, controlling reguklartory functions, hearing, vision
Overview from evelopment
1.
Diencephalon
2.
Midbrain
3.
Cerebellum
4.
Memorize the parts of the brain
-
The Brainstem
Frog brain is the size of a fetus brain
The dorsal part of the brainstem (above the ventricle) is sensory and the ventral part is motor
Epithalamus - seasonal rhythms (pineal gland)
1.
Thalamus - cortical relay system
2.
Drinking
a.
Eating
b.
Temperature regulation
c.
Sleep
d.
Salt regulation
e.
Sexual motivation
f.
Sexual behavior
g.
Stress
h.
Hypothalamus - regulatory behavior
3.
Hyperphagia (phagia to chew)
Ventromedial damage = obesity
Aphagia
Lateral damage = starving
Mediate our eating behavior
Lateral hypothalamus and Ventromedial hypothalamus
-
Diencephalon (The Rooms)
Each cluster
Thalamus = rooms
Superior colliculus - visual control
Collis = hill
Inferior Colliculus - auditory control
Tectum - roof is sensory
-
Midbrain or Mesencephalon
