Lecture Notes February 7, 2006 We will first
finish our discussion of last week of the brain
from the "top down" perspective that began with
the early work on phrenology and progressed
toward developing a more realistic view of how
major areas of the brain are involved in the
control of behavior and cognition. We will also
complete our discussion of some of the major
organizing principles by which the brain controls
behavior and interprets the world. Specific
topics remaining for the nervous system include
Limbic system Pleasure and aggression Split
brain work Neuroplasticity and
reorganization Given time, after concluding the
discussion of these major organizing principles
of the nervous system, we will begin our
discussion of the causes or factors that "move
us" or underlie or energize our behavior,
namely, our motivations. We will consider (or at
least start on) the following issues The major
functions of motivation (activation of the
organism and directing it toward a goal) A
typology of motivationsthe major types and an
interesting idea about how they relate to one
another Goal conflict and what happens when it
occurs The evolution of the adaptive mechanism
of homeostatic control and how control systems
operate. A basic model of the functioning of
primary (physiological) drives, how they fit into
the above model, and why they are so important
and adaptive
