3. Psychology 304 is partnering with the College
of Health Disciplines to offer you an
opportunity to engage in dialogue with students
from other disciplines regarding important
social issues at monthly Parisian Salons.
Parisian Salons were originally held in Paris
during the 18th and 19th centuries they were
gatherings of intellectual, social, political,
and cultural elites under the roof of an
inspiring host, partly to amuse one another and
partly to refine their taste and increase their
knowledge through conversation (Wood, 2012).

Major Divisions of the Brain

What are the primary structures found in each
division of the brain?
1. Myelencephalon (Medulla)

• Composed largely of tracts carrying signals
  between the brain and body.

• Contains
• The reticular formation (reticular activation
  system). Involved in vital functions arousal,
  sleep, maintenance of muscle tone, cardiac,
  circulatory, and respiratory reflexes.

2. Metencephalon

• In addition to the reticular formation,
  contains the

Pons. Relays sensory (e.g., face, mouth,
auditory, vestibular) and motor (e.g., face,
mouth, eye movement) information.
Cerebellum. Integrates sensory and motor
information to enable coordinated movement (e.g.,
walking)

3. Mesencephalon

• In addition to the reticular formation,
  contains the

Tectum. Auditory and visual localization.
Tegmentum. Substantia nigra (black substance)
influences voluntary movement red nucleus
influences face movement and limb movement.

4. Diencephalon

• Contains the

Thalamus. Relays sensory information sensory
gateway.
Hypothalamus. Regulates motivated behaviour,
controls release of hormones from the pituitary
gland, maintains bodily functions.

Thalamus and Hypothalamus
18
Pituitary gland. The master gland of the body.
Controls hormone secretion from varied glands.
Optic Chiasm. The point at which the optic
nerves that exit each eye come together.
