Bi12 Nervous System Part 2


What happens at the gap? -> Actual fusion of synaptic vesicles with the pre-synaptic membrane; movement of neurotransmitters, to receptors on the other side


after the action potential or electrical signal has traveled down the neuron it needs to get sodium back to the outside against the gradient and potassium inside, also against its concentration gradient
-this requires energy
