The Synapse
Captions available
The idea
A synapse is the junction where one neuron's terminal button communicates with the next cell across a narrow gap.
In practice
The terminal of one neuron sits fractions of a micron from the dendrite of the next, never touching it.
Where people slip
Neurons do not connect physically. The gap is the point, because it is where the signal can be modulated.
