Dopamine is a neurotransmitter produced by the nervous system that is involved in the pleasure/reward system in the brain. The release of dopamine in response to a stimulus produces feelings of happiness and satisfaction. Cocaine is a type of drug that affects the brain response to dopamine. Usually after dopamine is released into the synaptic cleft, it is quickly re-absorbed into the neuron using dopamine transporters. However, cocaine blocks these transporters which causes dopamine to remain in the synaptic cleft for a long period of time. How would this impact the neuron's ability to communicate? Neurons will produce smaller action potentials because more dopamine is binding to receptors on the neuron, preventing the neuron from reaching the threshold potential Neurons will be under-stimulated because dopamine will bind to receptors and prevent ions from moving into the neuron, preventing electrical signaling Neurons will produce larger action potentials because more dopamine is…
An individual diagnosed with CMT has difficulty holding a cup because: a. The myelin in the motor neurons is damaged thereby preventing an impulse frommoving along the axonb. The myelin in the sensory neurons is damaged thereby preventing an impulse frommoving along the axonc. The dendrites in the motor neurons are damaged thereby preventing an impulse frommoving along the axond. The dendrites in the sensory neurons are damaged thereby preventing an impulse frommoving along the axon
The monoamine hypothesis of depression proposes that monoamine oxidase is overproduced in very depressed people. O depression is a result of low monoamine levels at synapses. depression is a result of high monoamine levels at synapses. monoamine oxidase is absent in very depressed people.

Drugs which open Cl- channels in synapses :-a- cause depolarization of postsynaptic membraneb- cause hyperpolarization of postsynaptic membranec- enhance release of neurotransmitters from synaptic knobsd- enhance response of postsynaptic neurons
Imagine that a new type of psychoactive drug has been developed in a laboratory. It works by slowing the reuptake of dopamine in some brain circuits, increasing the amount of dopamine in the synapse. It also blocks serotonin binding in other brain circuits. Based on only this information, you can conclude that this new psychoactive drug is a: dopamine and serotonin antagonist. dopamine antagonist and serotonin agonist. dopamine and serotonin agonist. dopamine agonist and serotonin antagonist.
Studies have shown that individuals with attention deficit hyperactivity disorder (ADHD) may have lower than normal amounts of dopamine and norepinephrine excitatory neurotransmitters in their synapses. Methylphenidate is one of the drugs prescribed to individuals with ADHD. It prevents the reuptake of dopamine and norepinephrine neurotransmitters from the synapses, thereby keeping these neurotransmitters in the synapses longer. Which of the following rows correctly identify the effects of methylphenidate in individuals with ADHD? Select one: a. There is an increase in the permeability of the presynaptic neuron to potassium ions. b. There is a increase in the permeability of the postsynaptic neuron to potassium ions. c. There is an increase in the permeability of the presynaptic neuron to sodium ions. d. There is a increase in the permeability of the postsynaptic neuron to sodium ions.
Why does smoking marijuana produce a psychoactive response? O The active ingredient in marijuana, CBD, can bind to CB2 receptors in the periphery The active ingredient in marijuana, THC, can bind to CB1 receptors in the brain O The THC molecule is structurally identical to the endogenous cannabinoid anandamide O THC is a CB1 receptor antagonist Because life is just beautiful, man.
The big picture: draw two neurons in communication Label the presynaptic neuron, postsynaptic neuron and synapse. Label on both neurons: dendrites, axon, cell body Draw an arrow indicating the flow of information through both neurons Label where the electrical signal (action potential) travels Label where the chemical signal (neurotransmitters) travels
Briefly describe our brain's mesolimbic dopamine system. (A) Which brain structures are involved in this system? (B) What type of behavior does it regulate? (C) Even though social media (or video games and the like) isn't something ingested, do you think this system is involved in our social media behavior? Or do you think something else is involved? Please provide a brief, but specific response. Answer as much as you can please!!!!!!! Thank you!!!!!!
