Electrical synapses are specialized connections between neurons that allow direct communication through electrical signals. Unlike chemical synapses, which use neurotransmitters, electrical synapses enable rapid transmission of impulses by allowing ions to flow directly between adjacent cells. This type of synapse is particularly important in situations requiring quick responses, such as reflex actions. These synapses are formed by structures called gap junctions, which consist of protein channels that connect the cytoplasm of two neurons. Electrical synapses are found in various parts of the nervous system, including the brain and heart, facilitating synchronized activity among groups of cells.
