A new measure for the strength of electrical synapses [PDF]

Frontiers in Cellular Neuroscience, 2015
Electrical synapses, like chemical synapses, mediate intraneuronal communication. Electrical synapses are typically quantified by subthreshold measurements of coupling, which fall short in describing their impact on spiking activity in coupled neighbors.
