Gangliosides and Thermal Adaptation

  • Hinrich Rahmann
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 125)


The concentration and pattern of brain gangliosides of lower and higher vertebrates were compared. Only when considering the eco-factor temperature clear correlations between systematical position of species, thermal adaptation status and brain ganglioside composition can be shown: lowering of the environmental temperature induces a long-term formation of more polar ganglioside fractions. In fishes additional long-term compensatory effects to changes in temperature were demonstrated with regard to motor activity, bioelectrical activity of the CNS (post-synaptic potential amplitude) and avoidance conditioning-learning. All phenomena taken together reflect a mechanism of modulating the thermo-sensitivity of the membrane-mediated processes of transmission.
