How do our neurons work together to control behaviors?

This unit expands what students now understand about how neurons talk to each other, to take a look at more complex behaviors. Carrying on with the theme of using examples that students will find personally relevant, the unit begins by exploring the sleep-wake cycle. Students keep a sleep journal and use it to directly analyze how their brains are controlling their behaviors. Armed with their knowledge of how neurons in a circuit excite and inhibit each other, students finish the unit with an understanding of how the sleep wake cycle works, and how the quality of their sleep can influence their performance. The unit concludes with an investigation of what can happen when signaling between neurons is short-circuited during epilepsy.
