Question
Chapter 39.2, Problem 1TC
Summary Introduction
To determine:
The method how poison acts to disrupt the nerve function.
Introduction:
In an experiment, neurons are bathed in a solution containing nerve poison. The presynaptic neuron gets stimulated and produces an action potential, but it does not result in post synaptic potential in the postsynaptic neuron. When an individual adds neurotransmitter to the synapse, then also the postsynaptic neurons do not produce post synaptic potential.

Imagine an experiment in which the neurons pictured here are bathed in a solution containing a nerve poison. The presynaptic neuron is stimulated and produces an action potential, but this does not result in a PSP in the postsynaptic neuron. When the experimenter adds some neurotransmitter to the synapse, the postsynaptic neuron still produces no PSP. How does the poison act to disrupt nerve function?
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.

You are recording from two neurons in order to characterize the synapse that connects them. When
the presynaptic neuron (Neuron A) fires an action potential, the postsynaptic neuron (Neuron B) is
rapidly depolarized. You suspect that the synapse is electrical, and carry out the following
experiments to test your hypothesis.
A. When you try the converse experiment, and fıre an action potential in the Neuron B, you see a
depolarization in the Neuron A. Based on your understanding of the different kinds of synaptic
transmission does this support your hypothesis?
