The Fawn-Hooded (FH) rat carries a gene mutation that results in a dysfunctional serotoninergic system. However. previous studies have reported differing features between the FH/Wjd and FH/Har strains. We aimed to compare the behavioural and neurobiological features of FH/HamSlc rats with those of Fischer 344 rats. https://www.muttsandcoers.shop/product-category/immunity/
