Consciousness,
the Brain, and
Behavior
i
n this chapter, we discuss how
the nervous system determines
our states of consciousness and
the ways in which the brain produces
complex behaviors. Although recent
advances in electrophysiology
and brain-imaging techniques are
yielding fascinating insights, there is
still much that we don’t know about
these topics. If you can imagine
that, for any given neuron, there
may be as many as 200,000 other
neurons connecting to it through
synapses, you can begin to appreciate
the complexity of the systems that
control even the simplest behavior.
