Procerebrum

The cerebral hemispheres, with their bentricular hollows or lateral ventricles, the corpora striata, and the olfactory lobes,—a set of parts to which, as a whole, the name of procerebrum or prosencephalon may be given.

In several respects, the procerebrum is the most unusual region in the entire CNS. Its embryological origins are associated with those of the tentacle ganglion, and it only joins the rest of the cerebrum at a late stage in development (van Mol, 1974).

The terrestrial slug Limax has a highly developed olfactory center, the procerebrum, in which the LFP spontaneously oscillates,” scientists in Shido, Japan report.

The procerebrum is the equivalent structure to the lateral lobe in Hygrophila.

The median mass of the procerebrum is formed by the fusion of the procerebral lobes .
