Question

As part of a laboratory experiment in his psychology course, Miguel is observing the activity of a recording electrode on the axon of a neuron. As an action potential

occurs what might Miguel observe?

A The axon will release neurotransmitters into the synapse.

B. The avon will remain at threshold potential as negative ions continue to flood the cell.

OC The decial charge of the neuron will go from positive to negative before returning to threshold potential.

OD. The curical charge of the neuron will go from negative to positive before returning to resting potential

Answer 1

The correct answer is D

Step-by-step explanation:

A resting neuron has a voltage across its membrane, which is referred to as resting potential. This resting potential is caused by concentration gradients of ions across the membrane. A neuron returns to the threshold potential by the movement of positive ions (especially K+ ions) through channels that stay open to exit the neuron.
