ABSTRACT

Since Jackson, in an unsurpassable masterpiece described uncinate fits, there has been continued interest in the remarkable coincidence during the aura of smell and taste sensations and a dreamlike change of consciousness. Until now, brain pathology has contributed little more than the relevance of the Uncus to the cortical center of the olfactory sense. The question of the relation to dream and sleep has not been discussed. Nevertheless, in the last decade many basic studies have appeared on the pathology of Ammon’s Horn (Neuburger, Spielmeyer, E. Scharrer, etc.). It is the special merit of R. Altschul (Z. Neur. 140, 742, 1932) to have emphasized the morphology of the Uncus as an index of the extent of brain development. The cytoarchitectonics of the region have been described in great detail (v. Economo, Rose etc.), and especially, in the brilliant studies of Lorente de No. But all these and other studies of the archicortex touch on the physiological problem only from the above mentioned standpoint, though to be sure, A. Kappers emphasized the nature of archicortex as correlational cortex.
