(Phys.org)—A trio of researchers, two with Stockholm University, the other with the Konrad Lorenz Institute of Ethology in Austria, has found via experiments they conducted with guppies, that larger brain size in an organism may lead to a weaker immune system. In their paper published in Proceedings of the Royal Society B, Alexander Kotrschal, Niclas Kolm and Dustin Penn describe their experiments and results and why they believe other similar studies may one day prove that larger brained animals tend to have weaker immune systems than do those with smaller brains.
