title: Phylogenetic and regional variations in brain gangliosides of tetrapods.
abstract: 1. Ganglioside patterns were analyzed from four neural tissues (medulla, midbrain, forebrain and retina) in a representative from each of the four tetrapod classes. 2. Regional variations in ganglioside patterns were noted within some species, but differences were greater across phylogenetic lines. 3. These results suggest that evolutionary history plays a greater role than neural differentiation in the expression of brain ganglioside patterns.
