Unit 2 – Biological Basis of Behavior
2.3 Overview of the Nervous System and the Neuron
mixed difficulty
What happens during action potential within a neuron?
The neuron is flooded with calcium ions, causing it to contract.
There is a rapid change in electrical charge across the cell membrane, leading to a nerve impulse.
The neuron stops all activity and enters a resting state.
There is no significant change; action potential is simply when the neuron is ready to transmit an impulse.
