  • Look Inside

1) Degeneration of fibers was found in the Meynert's commissure by Marchi method after lesion in the medial part of the pontile teg-mentum in a series of the rabbit's brain. The degenerating fibers were traced from the yen-tromedial portion of the Forel's field to the dorsolateral part of the medial forebrain bun-dle; then they through the internal capsule to the optic tract. After crossing the median line, the fibers in question descend along the dorsal side of the optic tract, then through the cerebral peduncle, reaching the zona in-certa, and the ventral part of the lateral geniculate body.

2) The medial forebrain bundle showed de-generation after lesion of the ventral grey matter near the pontile raphe. The degenerat-ing fibers ascend from the dorsolateral part of the interpeduncular nucleus, then through the mediodorsal parts of the medial forebrain bundle, reaching for the most part the regio innominata, while only very few of them attain the septum pellucidum.

3) The myelogenesis of Meynert's commis-sure was also studied.
