Brain architecture: understanding the basic plan

How the brain works: structure and function

The simplest nervous systems: neurons, nerve nets, and behavior

Centralization and symmetry: ganglia and nerves

The basic vertebrate plan: nervous system topology

Brain and behavior: a four systems network model

The motor system: coordinating external and internal behaviors

The behavioral state system: intrinsic control of sleep and wakefulness

The cognitive system: thinking and voluntary control of behavior

The sensory system: inputs from the environment and the body

Modifiability: learning, stress, cycles, and damage repair

Gene networks: relationship to neural networks.
