Seasonal plasticity in telencephalon mass of a benthic fish

Journal of Fish Biology, 2014
To gain a deeper understanding of how environmental conditions affect brain plasticity, brain size was explored across different seasons using the invasive round goby Neogobius melanostomus. The results show that N. melanostomus had heavier telencephalon in the spring compared to the autumn across the two years of study.
