- Animals humans anatomy, physiology, behavior
- Tract tracing
- Single unit recordings
- Behavioral studies pharmacology

10Localization of function in the nervous system
Phrenology (Gall, early 1800s) 1.The brain is the
organ of the mind. 2. The mind is composed of
multiple distinct, innate faculties. 3. Because
they are distinct, each faculty must have a
separate seat or "organ" in the brain.

12What are we doing with our brains at this
moment?(The students brain)
- Feeling your chair
- Squirming (moving)
- Watching
- Listening
- Remembering
- Paying attention
- Sleeping
- Feeling anxious
- Feeling hungry
- What happens when you ask a question?

22The Brain is Composed of Discrete Cells Neurons
and Glia
23The Brain is Composed of Discrete Cells Neurons
and Glia
24Neurons communicate with each other primarily
through synapses
25Glia support and maintain neurons
- Protect by surrounding and buffering
- Speed transmission by forming myelin sheaths
