A nomenclature for the cortical sulcal features of the tammar wallaby, Macropus eugenii

A number of authors have suggested different nomenclatures for the sulcal pattern of the cortex of species from the macropodid family. These nomenclatures were found to be inadequate. This study proposes a simple and comprehensive nomenclature for the sulcal features of the cortex in wallabies. Prior to choosing the nomenclature, the most consistent sulcal pattern of the cortex of wallabies was determined. Also taken into consideration were results from both physiological and cyto-architectonic studies. The nomenclature chosen for the sulci is based upon the cyto-architectonic region in which they are found or which they delineate. This nomenclature can also be applied to other species from the family Macropodidae and, probably, more generally to metatherian mammals.
