Term
|
Definition
| Distance between neurons is small. Ions can flow direction from one neuron to the next. |
|
|
Term
|
Definition
| Greater distance between neurons. One neurons affects the activity of the other by releasing chemicals into the gap between them. Original distribution of ions is later restored by the sodium potassium pump. |
