Employing nerve preparations bathed in Ringer solution, the conduction velocity of a selected single myelinated fibre was measured in two cases, that is, when excited alone or together with other fibres.
In most of the experiments, the conduction time appeared larger when excited together than when excited alone. The difference obtained for a conduc tion distance of about 12cm. ranged from 0.13 to 1.58 msec. at room temperature 8-19°C. In few examples, the results were reverse or there was no change.
The velocity change was reasonably explained in terms of electrical interaction between nerve fibres; it was thus made probable that an interaction can take place between myelinated nerve fibres in situ.
