Role of Steroid Hormones on NA+-K+ Atpase Activity and Expression of ER and PR in the Brain of Oreochromis mossambicus

Over the past decade, it has become evident that the brain is a steroidogenic organ. The actions of hormones in the brain play important roles during early development and in the process of sexual differentiation. The effects of steroid hormones on dendritic morphology, synaptic function and ionic conductance have been implicated in the regulation of behaviour in both vertebrates and invertebrates.
