F. K. Studnička (1894): Fishes and amphibians also have the cerebral cortex

Abstract

The aim of this paper is to provide translation of probably the first report (Studnička 1894) demonstrating that the telencephalon of all vertebrate taxa (including fishes and amphibians) is characterized by the presence of the cerebral cortex (pallium). This report was one of those initiating a century-long and still not fully resolved discussion concerning homologies of various pallial subdivisions in different vertebrate taxa and probably the first to draw attention to the importance of careful study of the pallium in representatives of agnathans (Cyclostomes) such as lampreys (Petromyzonts) and hagfishes (Myxinoids). This article also briefly reviews the current status of comparative research on vertebrate telencephalon, and provides historical notes which position Studnička's report in its historical context. © Versita Sp. z o.o.
