In white matter regions of the brain and spinal cord of adult mammals, gap junctions previously were observed linking astrocytes to astrocytes, as well as to oligodendrocytes and ependymacytes. The resulting "functional syncytium" was proposed to modulate the ion fluxes that occur during electrical activity of the associated axons. Gap junctions also have(More)
Previously, synaptic activity in the spinal cord of adult mammals was attributed exclusively to chemical neurotransmission. In this study, evidence was obtained for the existence, relative abundance, and widespread distribution of "mixed" (chemical and electrical) synapses on neurons throughout the spinal cords of adult mammals. Using combined confocal(More)
