Psyc 375 Exam 2 Study Guide Questions with Complete Correct Answers | Grade A+

effector proteins Ans: proteins that have some direct effect on the behavior of the target cell excitable dendrites Ans: Boosts EPSPs EPSP summation Ans: a simple form of synaptic integration whereby excitatory postsynaptic potentials combine to produce a larger postsynaptic depolarization synaptic integration Ans: process by which multiple synaptic potentials combine within one postsynaptic neuron voltage gated channels Ans: open and close in response to changes in membrane potential back propagation Ans: A process by which learning can occur in a connectionist network, in which an error signal is transmitted backward through the network. This backward-transmitted error signal provides the information needed to adjust the weights in the network to achieve the correct output signal for a stimulus. postsynaptic membrane Ans: the cell membrane opposite the terminal button in a synapse; the membrane of the cell that receives the message Nero-receptors Ans: a membrane receptor protein that is activated by a neurotransmitter. Chemicals on the outside of the cell, such as neurotransmitter, can bump into the cell membrane and along the membrane we can find receptors. G-protein coupled receptors Ans: A special class of membrane receptors with an associated GTP binding protein; activation of a G protein-coupled receptor involves dissociation and GTP hydrolysis steps in neurotransmitter action Ans: 1. NTs synthesized from precursors by enzymes 2. NTs stored in vesicles 3. NTs that leak from vesicles are destroyed by enzymes 4. APs cause vesicles to ufse w/the presynaptic membrane and release their NTs into the synapse 5. Released NTs bind w/qutoreceptors and inhibit subsequent NT release 6. Released NTs bind to postsynaptic receptors 7. Released NTs are deactivated by reuptake or ED metabatropic receptors Ans: a G-Protein-coupled receptor whose primary action is to stimulate an intracellular biochemical response
