Pineal Gland ~ found in vertebrates; part of endocrine system1. Produces serotonin, a hormone that affects the modulation of wake/sleep
patterns and seasonal photoperiodic functions 2. Found in lamprey - primitive vertebrate. Not found in alligator – lost in

Frog
Human Brain
Limbic System Paleomammalian brain
A complex set of brain structures that lies on both sides of the thalamus, right under the cerebrum.1. Collection of structures from the
telencephalon, diencephalon and mesencephalon .
2. Includes the hippocampus, amygdala, anterior thalamic nuclei, septum, habenula, limbic cortex and fornix.
3. Supports a variety of functions, including emotion, behavior, motivation and long term memory, and olfaction.
4. Primarily responsible for our emotional life.
5. Critical role in the formation of memories.
Emotion !!!!!Involves the entire nervous system. Two parts of the nervous system are especially significant: 1. Limbic system 2. Autonomic nervous system:
Sympathethic Nervous System and Parasympathetic Nervous System
