Welcome to lesson three of the free Psychology 101 course! So far in this series, you have explored the fundamentals of what psychology is and how psychologists research the human mind and behavior. This lesson focuses on the biological processes that play a role in how we think, feel, react and behave.
Every year, millions of people are affected by disorders of the brain and nervous system including Alzheimer's, Parkinson's disease, stroke and traumatic brain injuries. These illnesses and injuries highlight the importance of the biological bases for our behavior. In this week's lesson, we'll explore some of the basics of biological psychology.
Syllabus for this week:What is biopsychology?

The Basics
The area of psychology that seeks to understand how the brain affects behavior is known as biopsychology, although you may also hear this subject referred to as psychobiology or behavioral neuroscience. Click the following link to learn more about some of the basics ofbiopsychology.
The NeuronNeurons are the basic building blocks of life. These highly specialized cells are responsible for receiving and transmitting information from one part of the body to another. In this article, you'll learn more about how neurons function. Click the link to start learning more aboutneurons.
Neuron Anatomy
In order to better understand how a neuron works to transmit information throughout the body, it is essential to know the different parts of a neuron. Learn about the structure of a neuron and how neural signals are transmitted in this overview of neuron anatomy.
NeurotransmittersYou've seen how a cell is structured and how nerve impulses are propagated down the cell, but how does this information travel from one cell to the next? Learn more these chemical messengers that transmit signals from one cell to the next in this overview of neurotransmitters.
Communication Systems
Neurons make up only a small part of the human body's complex communication system. The nervous system is composed of two main parts: the central nervous system and the peripheral nervous system. Additionally, the endocrine system plays an important role in communication. Learn more about these two important systems and the impact they have on the brain, the body and behavior in this article on the nervous and endocrine systems.
The BrainTechnological advances in recent years have allowed scientists to study the human brain in ways that were not possible in the past. Learn more about the different parts of the brain and the functions that each area serves in this tour of the human brain.
