PS 235 Fall 2016 Exam 1 Study guide Biopsychology as a neuroscience (chapter 1 and 2.1) -What are the 3 major biopsychology research characteristics and what does each side of each dimension actually mean? Know the advantages of human vs. nonhuman subjects and be able to differentiate between experiments vs. nonexperiments and they types of nonexperiments -What are the 6 divisions of biopsychology and how are they different from one another? -What are the major “dichotomies” of biopsychology? What are the details/evidence for each? Who were the major players in each and what did they believe? -What 3 things are intertwined to establish behavior? Anatomy of the nervous system (chapter 3) -CNS vs. PNS; somatic vs. autonomic NS; parasympathetic vs sympathetic NS; know function of each branch and the tree. Do they work together? -Know the difference between afferent and efferent nerves. Do they arrive or exit the CNS? -Know the 3 contributing players to CNS protection (meninges, CSF, blood brain barrier). What does each do? What are the specifics of each? -What are the 2 types of cells in the nervous system (neurons, glial cells)? What do they do? -What are the features of a neuron and what is each part responsible for? Be able to label them on a picture and know the order of incoming signals. -What are the 4 types of neurons and how does their physical appearance differ from one another? -What are they 4 types of glial cells? What does each type of cell do? Where are they located? -Know and be able to apply the neuroanatomical directions (dorsal vs. ventral; anterior vs. posterior; medial vs. lateral) -Know the divisions of the brain and be able to label each region on a picture. Know the details of the cerebral cortex (know the 4 lobes, what they do, major items that divide them). Know the function of each brain region (limbic system, basal ganglia, thalamus, hypothalamus, tectum, tegmentum, cerebellum, pons, medulla, reticular formation). Be able to label the parts of the brain stem. Neural conduction and synaptic transmission (chapter 4) -What is the resting membrane potential? What does that number actually mean? Why is it important? -What ions are involved in the resting membrane potential? Where are they each more concentrated? -What are the 4 factors responsible for maintaining the resting membrane potential? Be able to describe them and know how they are acting on each ion. Don’t forget about the Na+/K+ exchange pump and the specifics of it. PS 235 Fall 2016 -Which ions are involved in the action potential? What is the flow of ions during the action potential? -What are postsynaptic potentials? What are excitatory vs. inhibitory postsynaptic potentials? What doe hyperpolarization and depolarization mean? How does that play into postsynaptic potentials? -What is the threshold of excitation? What is the numerical value? What happens at this voltage? -What is an action potential? Be able to describe and draw the action potential including when ion channels open and close and the phases (figure 4.5). -What is the importance of voltage gated ion channels? -What are the absolute vs relative refractory periods? What are they responsible for? -What is saltatory conduction? How does it impact the speed of conduction down an axon? -How do neurons communicate? Down an axon/inside the neuron? Across a synapse/between neurons? -What are the parts of the synapse? -What are the differences between small and large neurotransmitters? -How are neurotransmitters released? What is it called? How does it work? What ion is important here? Be able to describe this process in detail. -What is the importance of receptors? Where are they found? What do they do? How do they work? What are they differences between ionotropic and metabotropic receptors? -Describe the 2 ways in which postsynaptic potentials are terminated -What are the classes of small molecule neurotransmitters (NTs)? Which NTs fall in which groups? Why are they grouped in this way? What are they major ones in each group? What are the differences between groups? Catecholamines vs indolamines? Function of each group/NT?
