The water content, apoptosis, and proliferation of the brain in marine medaka affected by seawater acidification
Abstract A possible explanation for ocean acidification‐induced changes in fish behavior is a systemic effect on the nervous system. Three biological barriers at the blood–brain interface effectively separate the brain from the body fluids. It is not known whether fish brain regions in contact with...
