Gunnar Nils Toivo Svaetichin was a Swedish-Finnish-Venezuelan physiologist known for his significant contributions to the understanding of fish retinas and vision. In 1956, he demonstrated the sensitivity of electroretinograms to blue, green, and red wavelengths, supporting the Young-Helmholtz trichromatic theory. He also introduced the S-potential concept, providing experimental evidence for the opponency in visual processing. Born in Finland in 1915, he later moved to Sweden and worked as a researcher in Venezuela until his passing in 1981.
