Electrical synapse Electrical synapse An electrical synapse is a mechanical and electrically conductive link between two neighboring neurons that is formed at a narrow gap between the pre- and postsynaptic neurons known as a gap junction. At gap junctions, such cells approach within about 3.8 nm of each other, a much shorter distance than the 20- to 40-nanometer distance that separates cells at chemical synapse. In many animals, electrical synapse-based systems co-exist with chemical synapses. Compared to chemical synapses, electrical synapses conduct nerve impulses faster, but, unlike chemical synapses, they lack gain—the signal in the postsynaptic neuron is the same or smaller
Journal of Physical and Chemical Reference Data "Journal Citation Reports", the journal has a 2017 impact factor of 3.510. Journal of Physical and Chemical Reference Data The Journal of Physical and Chemical Reference Data is a quarterly peer-reviewed scientific journal published by AIP Publishing on behalf of the National Institute of Standards and Technology. The objective of the journal is to provide critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. The editors-in-chief are Donald R. Burgess, Jr, and Allan H. Harvey. The journal is abstracted and indexed in the Science Citation
