✦ Synopsis

The conduction of nerve impulses within the pineal system of the frog has been investigated. Uninterrupted transmission of nerve impulses was seen after electrical stimulation of the intracranial pineal tract and recording of action potentials from the extracranial portion of the pineal nerve. The conduction velocities were at 2--9 m/sec (medullated fibres of 3--8 ~ diameter), 1--2 m/see (intermediate group, 1--3 ~z) and 0.2--0.9 m/sec (unmyelinated fibres, 0.2--0.8 9).
