This lecture explores behavior from
the biological point of view. Of
particular interest are the brain and
nervous system.
THE NEURON: THE BUILDING BLOCK OF THE NERVOUS SYSTEM:

THREE BASIC KINDS OF NEURONS ARE (1) SENSORY, (2) ASSOCIATION, AND (3) MOTOR.
When a neuron releases neurotransmitters it is called
”Depolarization”.
When a neuron depolarizes, it alternates from
(1) a resting negative electrical potential to
(2) a positive electrical potential, and (3) returns to a
negative electrical potential again.
A nerve is a bundle of axons. Think of the axons as
thin rope fibers and the nerve as the thick rope itself.
Nerves are identified as afferent or efferent.
Afferent nerves move toward an objective.
Efferent nerves move away from a source.

- Does the Right Side Know What the Left Side is
Doing?
- The right hemisphere mediates nonverbal
patterning (sometimes called the “romantic”
hemisphere).
- The left hemisphere mediates verbal and
mathematical thinking (sometimes called the
“logical” hemisphere)
Sensation refers to the raw data of experience.
Psychology considers it important to study the
process of sensation, the basic process by
which we obtain information about external
reality.
