About 10%of the brain is neurons; about 90% is glia (Greek word for glue) Big Idea- The Seven Main Neurotransmitters 1. Serotonin - Involved in mod, sleep and appetite. 2. Dopamine - Involved in control of movement and sensations of pleasure. (related to Parkinson’s and Schizophrenia) 3. Acetylcholine - Involved in arousal, attention, memory, and controls muscle contractions. (related with Alzheimer’s) 4. Endorphins - Involved in pain relief (this is a natural opiate) 5. Norepinephrine - Involved in arousal and mood. 6. GABA - Involved in sleep and inhibits movement. 7. Glutamate - Involved in learning, memory formation, nervous system development, and synaptic plasticity. Big Idea- Three main Types of Neurons Efferent (motor neurons)- what allows you to do actions such as moving a finger or limb. Afferent (sensory neurons)- sense of feeling such as pain Interneurons (90%) Neuroplasticity The ability within the brain to constantly change both the structure and function of many cells in response to experience and trauma.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
