Abstract
Acclimation of goldfish at 35°C increased the cerebellar content of aspartate, glutamate, and taurine and [3H]glutamate uptake. Acclimation at 4°C increased the levels of glutamine, serine, and alanine and glutamine synthetase (GS) activity. Adenosine content increased in cerebellum of fish acclimated to warm temperature. K+-evoked release of endogenous and exogenous glutamate from cerebellar slices increased in fish acclimated at 35°C compared to 4°C. The basal level of cyclic adenosine 3′:5′-monophosphate (cAMP) in perfused cerebellar slices in fish acclimated at 35°C was much higher than in fish acclimated at 5° and 22°C. It is concluded that variations of environmental temperature produces large neurochemical changes in goldfish cerebellum.
