1. In a few sentences, describe Ionotropic receptors and Metabotropic receptors and briefly discuss the functional differences between them. 2. Given that the brain is insensitive to the energies in the external world in their raw forms, in a sentence or two describe how this problem is solved by sensory systems Next consider this: neuron potentials are the same everywhere in the brain, that is, an action potential is an action potential no matter where we find it. Explain, what causes us to have different sensory experiences from light, vibrations in the air, or chemicals in our mouths. 3. Describe the nature and identifying features of autism, its incidence in the population, and what is known about its neural and genetic basis. Try to limit your yourself to no more than 3-4 succinct, well written paragraphs. 4. List and briefly explain the 8 steps in synaptic transmission. Pick one psychoactive drug and explain how it affects synaptic transmission (see mechanisms of drug action chart) and how these effects on synaptic transmission might produce the drug’s psychoactive effects. 6. What two major components make up the nervous system of vertebrates like us? What two components make up each of these major subdivisions? What are the 5 major divisions of the brain (the Latin names)? List the brain structures in each of these divisions of the brain and in a two or three words tell the function of each brain structure. 7. What neurontransmitter is involved in both schizophrenia and Parkinson’s Disease? What is its role in each of these brain disorders? Briefly describe the major evidence for the involvement of this transmitter in these disorders. 8. List the parts of a neuron and what each part does. List the parts of a typical synapse and what each does. 9. According to Dr. K’s book, Mind Design, Chapter 9, what is emotion?
