Quiz 4 Synaptic Transmission and Neuropharmacology Please circle the correct answer for each question. You can only pick one option per question. 1. Which statement about the mechanisms of agonists or antagonists is correct: a) A drug that mimics the effect of a given neurotransmitter is called an agonist. b) An antagonist neutralizes the effect neurotransmitters by preventing their release at the presynapse. c) An antagonist binds to a specific receptor and predominantly causes inhibitory effects at the postsynapse. d) Agonists and antagonists have to bind to specific neurotransmitters in the synaptic cleft first before they dock at their postsynaptic receptors together. 2. Which of the following receptors are cholinergic receptors: a) AMPA and NMDA b) CB1 and NMDA c) Muscarinic and nicotinic receptors d) D1 and D2 3. The following lists some of the nuclei in the brain which are considered to be the major source of specific neurotransmitters. Which of these lists the correct pairing of nuclei to transmitter? a) Substantia nigra pars compacta & ventral tegmental area: dopamine Locus coeruleus: acetylcholine Nucleus basalis, neostriatum, & pedunculopontine nucleus: norepinephrine b) Substantia nigra pars compacta & ventral tegmental area: dopamine Locus coeruleus: norepinephrine Raphe nuclei: serotonin c) Raphe Nuclei: GABA Nucleus basalis, neostriatum, & pedunculopontine nucleus: dopamine Ventral tegmental area: glutamate d) Raphe Nuclei: dopamine Locus coeruleus: Norepinephrine Hypothalamus: GABA

Name: _______________________ 4. Which of the following statements about the effects of neurotransmitters is false: a) Parkinson’s disease is associated with severe degeneration of neurons in the raphe nuclei. b) Every effective antipsychotic drug can act as dopamine agonist. (...
