What is the charge of the inside of a neuron when at resting potential?

Negative, think no redt for the wicked

What happens during depolarization?

sodium in, potassium out. The neuron is becoming positive.

What is action potential?

a neural impulse; a brief electrical charge that travels down an axon. Once it reaches +30mV it must be transmitted.

What is repolarization?

Sodium (positive) gate closes.

——Think the neuron is repoing it's negativity so it cuts off the positives access

refractory period

Too much negativity prevents another action potential. (Refractory) (Refrain)
