Signalling across chemical synapses ... case of hyperpolarizing currents. Whether a synapse is excitatory or inhibitory depends on what ...

Dendrite

... In such dendrites the voltage change that results from stimulation at a synapse may extend both towards and away from the soma. In other dendrites, ... from many others, particularly those that input only weakly (more at synapse ). This integration is in aspects "temporal" -- involving the summation of ...
