1.Name the major neurotransmitters, identify what they do, and understand why they are important. Acetylcholine stimulates muscle contractions, memory, sleeping, and dreaming. Dopamine is involved in learning, movement, motivation, emotion, and pleasure. Endorphins are with exercise, orgasm and spicy foods. GABA or gamma-amino butyric acid is the brain. Glutamate is msg that is found in foods and serotonin is involved with mood, appetite and sleep. 2.Identify and describe the structures and functions of the cerebral cortex, including the four lobes and two hemispheres . The two hemispheres are the left and the right hemispheres. The first lobe is the frontal lobe which includes thinking. Planning, memory and judgment. Parietal lobe is the second lobe that gives information about in touch. The occipital lobe gives visual information. Lastly, the temporal lobe involves hearing and language. 3.Identify the basic structures of a neuron, the function of each structure, and how messages travel through the neuron. Cell body or the soma is the nucleus of the cell and keeps the cell alive. The dendrite collects information from other cells to send it to the soma. The axon transmits information away from the soma toward other neurons. To transport messages neurotransmitters, carry the message in them and send it to the next neuron then the neurons are separated by a synapse. 4.Describe   the   major   parts   of   the   nervous   system   and   their functions . The CNS and the PNS. The CNS which is the central nervous system that is the brain and spinal cord. The CNS controls all processing and interpretation of sensory   information   and   our   responses   to   the   information.   The   PNS   is   the peripheral nervous system is the motor and sensory neurons. The PNS links the CNS to the body’s sense receptors, muscles and glands.

5.Explain   and   define   the   concepts   brain   neuroplasticity, neurogenesis, and brain lateralization. Neuroplasticity is the brains ability to change its structure and function in response to experience or damage. Neurogenesis is the forming of new neurons. Brain lateralization is that both sides of the brain are specialized to perform different tasks.

    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.
