The influence of temperature in the neuronal development of tilapia, Oreochromis mossambicus.

The structure and functions of brain show sexual dimorphism in vertebrates. Brain sexual differentiation is resulted from the neural development. The neural development is determined not only by the genetic regulation, but also by the extrinsic environmental influences. Serotonin (5-hydroxytryptamine, 5-HT ) functions as a neurotransmitter or/and neuromodulator in the central nervous system. Serotonin plays a role in the neural development via serotonin receptors. The sexual differentiation of tilapia is influenced by water temperature. The lower temperature induces a higher proportion of female while the elevated temperature induces a higher proportion of male in tilapia. In the present study, the influence of temperature on the proliferation of the neurons was investigated. These results show that the proliferation of neurons are varied with the temperature. The elevated temperature influences the proliferation of neurons via central serotonin system. Serotonin 1A receptor is involved in the serotonin-induced proliferation of neuron.
