A series of local potentials causes the membrane potential to move to -80 mV. Predict the result.
A) Threshold is reached.
B) Depolarization occurs.
C) The neuron is hyperpolarized.
D) Information of frequency is needed to predict the result.
E) The neuron releases neurotransmitter in response.

Question

Quizplus · Accepted Answer

The neuron is hyperpolarized because a membrane potential moving to -80 mV indicates an increase in the negative charge inside the neuron compared to the resting membrane potential, which is typically around -70 mV. Hyperpolarization makes the neuron less likely to fire an action potential.
