The effects of alcohol are not fully understood but it does seem to inhibit GABAnergic neurons. How would the release of dopamine from the postsynaptic neuron change in this case? Explain your answer, being sure to make each connection between concepts
Step by step
Solved in 2 steps
- We talked about drug effects on neurons in sequence. The effect of alcohol is multi-faceted and the following question asks you to apply your knowledge. Imagine two neurons in sequence. The presynaptic neuron is GABAnergic and the postsynaptic neuron is dopaminergic. The effects of alcohol are not fully understood but it does seem to inhibit GABAnergic neurons. How would the release of dopamine from the postsynaptic neuron change in this case? Explain your answer, being sure to make each connection between concepts clear. If alcohol instead inhibited dopaminernergic neurons, in what way might the ion flow change in the dendrites of the postsynaptic neuron of this example?L-Dopa One of the first medications developed to treat Parkinson's disease is a substance called L-DOPA (or Levodopa). This medication can be taken to reduce the motor symptoms of Parkinson's. Unfortunately there is no way to reverse or stop the death of the dopamine producing neurons, but L-DOPA is one of a few treatments that can help manage the symptoms. Your task is to investigate what L-DOPA is and explain why taking L-DOPA might reduce the symptoms of the disease. Write at least one paragraph (5 sentences) to explain your findings in the box below. Use the rubric here to make sure you are explaining the situation thoroughly. This should be entirely in your own words. Do not use phrases from the internet if you do not know what they mean. Rubric (use to check your work) Has major the main points misconceptions not understand of this topic Shows a Understands Clearly does complete understanding How do Neurons 100 85 70 50 use neurotransmitters like dopamine? What do neurons do when…Cocaine blocks the removal of dopamine from the synapse, leading to a rapid rise of dopamine in the synapse. Which of the following best describes what will likely occur as a result of increased dopamine in the synapse? The presynaptic cell will be unable to release more neurotransmitter. the postsynaptic cell will return to its resting potential, causing feelings of well-being. The postsynaptic cell will be constantly activated, causing feelings of euphoria. The postsynaptic cell will respond more quickly to a change in output of the presynaptic cell, causing feelings of euphoria. The buildup of neurotransmitter will activate the presynaptic cell, causing feelings of euphoria.
- Monoamine oxidase inhibitors (MAOIs) are drugs that inhibit MAO, the enzyme which normally would break down dopamine. If a patient were taking MAOIs, would you expect postsynaptic neurons that normally receive a dopamine signal to be more or less active?Chlorpromazine and Bromocriptine both have the affinity in the dopamine receptors of the Central Nervous System, Chlorpromazine is use to treat schizophrenia and psychosis whereas Bromocriptine is use to treat parkinson’s disease. Explain the action of these drugs in the dopamine receptor and why they have different effects and clinical use, knowing that they both act on the dopamine receptors.There are a broad range of anti-epileptic medications currently on the market, with different therapies prescribed for different types and severities of the condition. Given what you have learned about synaptic transmission, which of the following could be a potential therapeutic approach to prevent the spreading of neuronal excitation? (3 correct answers, select all that apply) O A voltage-gated calcium channel blocker/inhibitor selective to glutamate-releasing neurons. O A voltage-gated calcium channel blocker/inhibitor selective to GABA-releasing neurons. O A glutamate receptor blocker (antagonist). O A GABA receptor antagonist. O A glutamate reuptake inhibitor. O A GABA reuptake inhibitor.
- In some cases of ADD (attention deficit disorder) the impulsive, erratic behavior can be normalized with drugs that stimulate the central nervous system. Explain this finding in terms of neurotransmitter activity in the brain.Glutamate is NOT secreted into a bipolar cell. Which of the following could be a possible message received by the brain? stinky! sour... sweet! bright! loud! pressure ..Flaccid paralysis (resulting from the failure of muscles to contract), induced by the neurotoxin tubocurarine, occurs when this poison blocks the binding of: the inhibitory neurotransmitter melatonin to post-synaptic bicarbonate channels the excitatory neurotransmitter glutamate to post-synaptic calcium channels the excitatory neurotransmitter acetylcholine to post-synaptic sodium channels the inhibitory neurotransmitter glycine to post-synaptic chloride channels the excitatory neurotransmitter serotonin to post-synaptic potassium channels
- I am confused about the process of rod cells in the dark. In the dark, rod cells are unstimulated and therefore the sodium is able to enter and depolarize the cell, stimulating the release of glutamate to the bipolar cell. However, this increase in glutamate in the bipolar cell inhibits the release of action potential from the bipolar cell to the ganglion cell. This doesn't make sense to me because shouldn't there be an increase in action potential since the rod cells are supposed to function in the dark?Malathion is an insecticide commonly used in the horticultural industry. Many homeowners apply this chemical to their trees to rid them of infestation by aphids or other insects. Malathion is classified as an organophosphate insecticide. Exposure to malathion is very dangerous to humans and animals because it acts as an irreversible inhibitor of acetylcholinesterase. Predict what might happen to synaptic communication between cholinergic neurons if an individual or animal was poisoned with malathion, and clearly describe the mechanisms at work.where are the locations you can these neurotransmitters: Norepinephrine Epinephrine Serotonin Glutamate Gamma-aminobutyric acid (GABA) Acetylcholine
