Question

One issue with antidromic stimulation is that this stimulation can activate nearby neurons that may be driving our recording measurements. To ensure that this neuron does connect to the brain region of interest, the researcher performs the “collision test”, which uses the idea that two colliding action potentials “cancel out”. To do so, they monitor the neuron of interest and wait for the occurrence of spontaneous action potentials. Immediately after the spontaneous action potential, they stimulate at their brain region of interest and wait to see what they record from their neuron.
Which of the following results and interpretations is correct? (Indicate all that apply)
1. They observe nothing; they conclude that the neuron does project to this brain region.
2. They observe an action potential; they conclude that the neuron does project to this brain region.
3. They observe nothing; they conclude that the neuron may not project to this brain region.
4. They observe an action potential; they conclude that the neuron may not project to this brain region.

Answer 1

Answer:

Explanation:2.) They observe an action potential

Answer 2

Explanation:

Correct answer is

Explanation 2: They observe an action potential; they conclude that the neuron does project to this brain region.
