Thalamus
Most sensory infor goes first to the thalamus, which processes it and sends output to the cerebral cortex.
Cortex sends infor back for magnifying certain input.
Medial geniculate
part of the auditory thalamus and represents the thalamic relay between the inferior colliculus (IC) and the auditory cortex (AC).
Lateral geniculate
a relay center in the thalamus for the visual pathway. It receives a major sensory input from the retina.
hypothalamus
partly through nerves and partly through hypothalamic hormones, the hypothalamus conveys messages to the pituitary gland, altering its release of hormones. Damage to any hypothalamic nucleus leads to abnormalities in motivated behavior, fighting, or activity level.
pituitary gland
an endocrine gland. The anterior pituitary is a lobe of the gland that regulates several physiological processes (including stress, growth, reproduction, and lactation). The posterior pituitary
Hormones secreted from the pituitary gland help control: growth, blood pressure, certain functions of the sex organs, thyroid glands and metabolism as well as some aspects of pregnancy, childbirth, nursing, water/salt concentration and the kidneys, temperature regulation and pain relief.
post is part of brain.
optic tract
The optic tract (from the Latin tractus opticus) is a part of the visual system in the brain. It is a continuation of the optic nerve that relays information from the optic chiasm to the ipsilateral lateral geniculate nucleus (LGN), pretectal nuclei, and superior colliculus.
optic chiasm
the X-shaped structure formed at the point below the brain where the two optic nerves cross over each other.
