The differences between chemical and electrical synapses are given below:In chemical synapses, the transmission of signals is mediated by neurotransmitters. On the contrary, in electrical synapses, the presynaptic and postsynaptic neurons together form a channel called a gap junction that allows the flow of ions or current from one cell to another.Chemical synapses are comparatively slower in signal transmission than electrical synapses.Chemical synapses are more flexible than electrical synapses.In chemical synapses, there is a fluid-filled space in between the neurons called the synaptic cleft. Whereas, in electrical synapses, the pre and postsynaptic neurons form a channel called gap junction.
