Forebrain - Most complex. o Hypothalamus – is responsible for motivation of actions. Hunger motivation. Also responsible for sexual motivation. o Amygdala – Regulates emotions. o Hippocampus – Responsible for moving information back and forth in memory.

Broca’s - Wernicke's area is the region of the brain that is important for language development. It is located in the temporal lobe on the left side of the brain and is responsible for the comprehension of speech, while Broca's area is related to the production of speech. (Broca’s aphasia) Two hemispheres - The left side of the brain is responsible for controlling the right side of the body. It also performs tasks that have to do with logic, such as in science and mathematics. On the other hand, the right hemisphere coordinates the left side of the body, and performs tasks that have do with creativity and the arts. o Split-brain experiments Gazzaniga video Endocrine system – the system of ductless glands that secrete hormones and release them directly into the blood stream. o Four differences between hormones and neurotransmitters From ductless glands instead of from neurons Via the bloodstream instead of a synapse like neurotransmitters – how they move through the body They can go longer distances than neurotransmitters
