...Xing-He Weng; Peter M. Piermarini; Atsuko Yamahiro; Ming-Jiun Yu; Daniel J. Aneshansley; Klaus W. Beyenbach SUMMARY We present electrical, physiological and molecular evidence for substantial electrical coupling of epithelial cells in Malpighian tubules via gap junctions. Current was injected...

...N. M. Ewadinger; N. I. Syed; K. Lukowiak; A. G. M. Bulloch ABSTRACT Electrical coupling is a common means of cell-to-cell communication in both neuronal and non-neuronal tissues (Lowenstein, 1985). Within the nervous system, many electrically coupled neurones exhibit dye coupling (Bennett, 1973...

...), are electrically coupled to each other as well as to a large number of foot and body wall motoneurones, forming a fast-acting neural network which coordinates the activities of foot and body wall muscles. The left and right sides of the body wall of Lymnaea are innervated by left and right cerebral A cluster...

.... Strong dye coupling and non-rectifying electrical coupling were observed between the contralateral homologues. No action potentials were recorded from the cell body, but postsynaptic potentials and slow potential changes (>1s, >15 mV) were observed. Upon injection of hyperpolarizing currents...

... the neuropile became hyperpolarized through the activity of an electrogenic sodium pump. When any T cell was hyperpolarized by 25 mV by repetitive stimulation, hyperpolarization failed to spread to the T cells to which it was electrically coupled. Further evidence for double rectification of junctions linking T...

... electrically-coupled neurones. In recent years two new methods (photoinactivation after Lucifer Yellow injection and intracellular injection of pronase) have been employed to delete selectively single neurones or small groups of neurones from neural circuits. These techniques have been successfully used...
