However chemical synapses transmit a signal with constant strength or even a signal that get stronger. This is called gain.. Electrical synapses are faster but have no gain, the signal gets weaker as it travels along the synapse to other neurons.Electrical synapses are only used for applications where a reflex must be extremely fast.
