NEURONS

NEURONS

· Specialized cells for the reception, conduction, and transmission of electrochemical signals

· Many sizes and shapes

- There are about one hundred billion neurons in the nervous system.

- Neurons are some of the longest-lived cells in the body.

- Neurons are irreplaceable.

- Neurons have huge appetites. About twenty-five percent of the calories that you take in every day are consumed by your brain's activity.

THE CLASSES OF NEURONS

Overview

This chapter discusses the structure and function of neurons and synapses, detailing various types of neurons, the concept of neuronal transmission, and the influence of neurotransmitters on behavior. It also examines psychopharmacology and the effects of psychoactive substances on mental processes.

Key Points
