Introductory Psychology Open Course: Unit 3
Biological Bases of Behavior
In this unit we'll look at the basic building blocks of communication within the body, which are neurons and neurotransmitters, then we'll look at the brain's key structures and their functions, and how researchers attempt to understand the role of genes in shaping behavior.


The parts of a neuron & their functions

How messages travel within a neuron

How messages travel between neural synapses

Processes that occur after neurotransmitter release

Introduction to key neurotransmitters and their associated functions

How other chemicals can influence neurotransmitter release

The divisions and subdivisions of the nervous system

How early researchers attempted to study brain function

Introduction to brain scanning; EEG, CAT, MRI, PET, fMRI, & DTI

Structure of the hindbrain and their functions

Structure of the midbrain and their functions

The subcortical structures of the forebrain and their functions

The cerebral cortex and associated functions of each lobe of the brain

Split-brain patients and severing the corpus callosum

Concepts for discussing genetics and shared genes

What a heritability score indicates about the role of genes

Examples of chromosomal abnormalities & molecular genetics
