PSYC 375 Exam 2 Study Guide- Questions and Complete Solutions

effector proteins proteins that have some direct effect on the behavior of the target cell excitable dendrites Boosts EPSPs EPSP summation a simple form of synaptic integration whereby excitatory postsynaptic potentials combine to produce a larger postsynaptic depolarization synaptic integration process by which multiple synaptic potentials combine within one postsynaptic neuron voltage gated channels open and close in response to changes in membrane potential back propagation 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 the cell membrane opposite the terminal button in a synapse; the membrane of the cell that receives the message Nero-receptors 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 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 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
