Consciousness

In this section, we will study consciousness in a number of forms. First, will explore what consciousness is and whether feeling like we consciously caused an action to occur means we actually did cause it.

Then, we’ll learn about the processes of sleep and the major theories of why we sleep. There are a number of disorders that can result when these processes go awry, and we will categorize these disorders according to the stage of sleep in which they occur.

Next, we will learn about various drugs that have effects on consciousness.

Finally, we will consider the effect meditation and hypnosis on consciousness and other outcomes.

The Basics
