Figure A4. Effects of perinexal width on ephaptic coupling (Na+ channel cluster inside the perinexus), for G gap = 25.3 nS (1% of normal).

The gap junction plaque (green) and its perinexus (grey) are located close to the centred Na+ channel cluster (red), such that the Na+ channel cluster is inside the perinexus. Same protocol, analysis and layout as in Fig. 7.
