...Candida M. Reed ABSTRACT Dye coupling between the cone-shaped radial muscle fibres, which control the expansion and closing of a squid chromatophore organ, was investigated in the squid Loligo vulgaris. Particular attention was paid to the role of the myomuscular junctions located between...

...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...

.... 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...
