[High permeability of the intercellular contact].
The mechanism of the intercellular contact (gap junction) high permeability is proposed on the following basis: 1) cell membranes are depolarized in the junction zone and 2) during depolarization a sharp increase of membrane permeability results from the formerly proposed [1--3] relationship between the trans-membrane potential and membrane surface potential (boundary jump), owing to the fact that the latter determines both the membranes conductance and conformation.
