Do neurons generate monopolar current sources?
... As a consequence, when ionic channels open (such as the postsynaptic currents indicated in Fig. 1), the setting of extracellular current and return current will not be instantaneous, and there will be a transient time during which charges will accumulate in the postsynaptic region. During this trans ...

Nerve Impulse Transmission
... Transmission at the Synapse • There is a tiny gap between the synaptic knobs of one neuron and the dendrites of the next one. • This gap is called the synapse or synaptic cleft. • The nerve impulse needs to cross this gap and it does so by the release of special chemicals called neurotransmitters. ...
