Some fish are able to select up on complicated tasks more rapidly than others, and researchers formerly attributed these individuals smarts to bulkier brains. Research study released July 13 in Proceedings of the Royal Society B finds that some individual distinctions in cognitive capability amongst fish of the exact same species might stem from relative size distinctions in between specific brain areas, not simply brain size total (289:20220844, 2022). The telencephalon is a brain area associated with cognitive skills including memory and decision making, while optic lobes are brain areas that process visual information.So Triki picked guppies (Poecilia reticulata) with small or big telencephalons and optic lobes.”She then compared the brains of the two groups and found that, while the average brain size remained the very same in between the two, fish with bigger optic lobes stood out at the initial color discrimination job.”Patton says that she appreciated that the research study focused on brain regions, rather than the brain as a whole.
