Chapter 2 Outline
Introduction: Electrical Storm
PART I The Cellular Components of the Nervous System
The Nervous System Contains Several Types of Cells
The neuron has four principal divisions
Information is transmitted through synapses
BOX 2.1: Visualizing the Cellular Structure of the Brain
The axon integrates and then transmits information
Glial cells protect and assist neurons
PART II The Large Scale Structure of the Nervous System
The Nervous System Extends throughout the Body
The peripheral nervous system has two divisions
The central nervous system consists of the brain and spinal cord
BOX 2.2: Three Customary Orientations for Viewing the Brain and Body
PART III The Functional Organization of the Nervous System
The Brain Is Described in Terms of Both Structure and Function
The cerebral cortex performs complex cognitive processing
Important nuclei are hidden beneath the cerebral cortex
The midbrain has sensory and motor components
The brainstem controls vital body functions
Networks of connections between brain regions determine behavior
Specialized Support Systems Protect and Nourish the Brain
The brain floats within layers of membranes
The brain relies on two fluids for survival
SIGNS & SYMPTOMS: Stroke
Brain-Imaging Techniques Reveal the Structure and Function of the Human Brain
CT uses X-rays to reveal brain structure
MRI maps density to deduce brain structure with high detail
Functional MRI uses local changes in metabolism to identify active brain regions
PET tracks radioactive substances to produce images of brain activity
RESEARCHERS AT WORK: Subtractive analysis isolates specific brain activity
Magnetism can be used to study the brain
