Ordinarily, patients with advanced Parkinson’s disease (who have damage to dopamine-releasing axons) move very slowly if at all. However, during an emergency (e.g., a fire in the building), they may move rapidly and vigorously. Suggest a possible explanation.
An undisclosed drug (Drug A) is a drug that can block voltage-gated K+ channels when being introduced into the bloodstream.
Explain the effects of Drug A on the action potentials produced by a neuron. If Drug A could be applied selectively to a presynaptic neuron that releases an excitatory neurotransmitter, analyse how would it alter the synaptic effect of the neurotransmitter on the presynaptic cell.
Remark: The word count limit (250 words only), no less than 100 words
The effects of neurotransmitter binding are very brief. Explain.

- 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.arrow_forwardWhat ion/s is/are most likely to have a high conductance through the Jerrionin channel?arrow_forwardWhat type of synaptic potential (if any; be sure to indicate if any modification is occurring as well) would occur if: a.) An MAO inhibitor type of antidepressant is functioning at an active dopaminergic synapse that increases the rate of sodium flowing into the cell. b.) Prozac is present at an active serotonin synapse where receptor activation increases the flow of potassium out of the cell.arrow_forward
- Action potentials are changes in membrane potential that are localized to a small area of the plasma membrane. However, an action potential can trigger the formation of a new action potential nearby. This cycle can repeat to produce conduction of the action potential down the length of the axon. Explain this process.arrow_forwardAs dopamine neurotransmitters are also responsible for producing feelings of euphoria (pleasure), many people affected with Parkinson's disease suffer from depression. A common treatment for Parkinson's is Levodopa, a chemical that turns into dopamine when it passes into the brain. From what you have learned about synapses, explain if people being treated with Levodopa for Parkinson's symptoms would require additional treatment for depression?arrow_forwardAntiseizure drugs stop seizures from happening by inhibiting electrical impulses. What is the importance of sodium and calcium channels on a neuron and reasons why actions potentials do not occur when these channels are inhibited.arrow_forward
- nerve axon has an absolute refractory period of 0.6 ms and a relative refractory period of 0.8 ms, explain what will happen if an action potential is elicited at the following time periods after the original action potential is produced at time equal to zero.arrow_forwardCan you explain to me why choice E is the correct answer and break down why the other options are false?Select the choice option that is TRUE regarding the absolute and relative refractory periods of the action potential (AP). A. The absolute refractory period occurs when the activation gate of voltage gated sodium channel closes at the peak of the AP B. The relative refractory period occurs when the inactivation gate of voltage gated sodium channels closes at the peak of the AP C. The relative refractory period occurs when the activation gate of voltage gated potassium channels opens at the peak of the AP D. The absolute refractory period may be overcome if enough excitatory stimulation is applied to the neuronal membrane E. All of the choice options are FALSE regarding the absolute and relative refractory periods of the AParrow_forwardI have stimulated a neuron with dopamine for a second followed by treating it with cocaine and calcium chelating agent (which chelates out all calcium from the system making them unavailable for function), what will be the effect of such impulse on generating an action potential in the post-synaptic neuron? Will it be different if I pretreat the set of nerve cells with cocaine and calcium chelating agent followed by stimulating the neuron with dopamine? Justify your answer with proper reasoning in brief.arrow_forward
- 1) A 100-um diameter nerve axon has the following properties: rm = 2.5 x 104 ohm x cm, ri = 1 x 105 ohm/cm, r0 = 0, cm = 3 x 10-8 F/cm. The permeability to Cl- is very high and Cl- ions are at resting potential Vm. A steady inward current is injected into the axon resulting in a Vm of -110 mV at the site of current injection. If the Vm 3 mm from the site of injection is -94.5 mV, what is the resting Vm?arrow_forwardIs an action potential more or less likely under these conditions? Explain.arrow_forwardTru or false Inhibitory synapses cause depolarization, leading to the possibility of an action potentials formation.arrow_forward
