Responsible for planning sequences of behavior and for certain aspects of memory and emotional expression. b. Hippocampus: critical for storing certain kinds of memories but not all. 2.

Hypothalamus: Through nerves and hormones conveys messages to the pituitary gland altering its release of hormones. B. Midbrain (Mesencephalon): Tectum, tegmentum, superior and inferior colliculus a.
