Intracerebroventricular (ICV) injection of streptozotocin (STZ) is a well established procedure to induce neuroinflammation leading to dementia in experimental animals. There are unique hypothalamic fatty acid (FA) sensing systems in fish that are different from those in mammals. An enhancement of glucose metabolic alteration by intracerebroventricular injection of TNF occurred probably because plasma glucagon levels were increased as a result of an increase in catecholamine levels .
