NAME DATE Mouse Party Worksheet Use the information in the activity to complete the table. For Sketch, make a drawing that summarizes the action of the drug. Drug Neurotransmitter(s) What does the drug do? Sketch Heroin Heroin mimics natural opiates by binding to opiate receptors in the brain, especially in areas related to pain, reward, and emotions. This binding inhibits the release of neurotransmitters like GABA Ecstasy Ecstasy affects the serotonin pathways that regulate mood, sleep, perception and appetite, by increasing the release of serotonin in the synapse, which causes an overstimulation of the cells. Marijuana When anandamide activates cannabinoid receptors, it turns off the release of inhibitory neurotransmitters, allowing dopamine to be released With GABA’s inhibitory effect turned off, dopamine oods the synapse, leading to intense feelings of euphoria Ecstasy interacts indirectly with the reward pathway. The excessive release of serotonin stimulates a milder release of dopamine in this pathway, which gives ecstasy slightly addictive properties. THC, the active compound of marijuana, imitates anandamide by binding to cannabinoid receptors, extinguishing inhibition and allowing the release of dopamine in the synapse. Unlike anandamide, THC does not decompose quickly 1 Drug Excess dopamine in the cell causes dopamine transporters to work in reverse, pumping dopamine out of the cell and into the synaptic cleft. What does the drug do? Sketch Excess dopamine is trapped in the synaptic cleft, which results in repeated binding to the receptors and causes an overstimulation of the cell, generating intense feelings of euphoria and energy associated with the use of methamphetamine. fi Methamphetamine Neurotransmitter(s) Alcohol Cocaine LSD Cocaine blocks dopamine transporters, leaving dopamine trapped in the synaptic cleft. This causes dopamine to repeatedly bind to the receptors, overstimulates the cell and generates intense feelings of euphoria. LSD acts almost exclusively on serotonin neurons, since it is chemically similar to serotonin and binds to its receptors. Alcohol enhances the effects of the GABA inhibitory neurotransmitter, causing the brain to become more sedated. At the same time, it blocks glutamate, an excitatory neurotransmitter, reducing brain activity. Cocaine is concentrated in the reward pathway of the brain and also affects the part of the brain that controls voluntary movements. This causes cocaine users to be restless and have dif culty staying still. fi GABA and Glutamate. LSD interacts with speci c serotonin receptors, but not always in the same way; sometimes it inhibits them and sometimes excites them. 2
