Although the levels of amino acid neurotransmitters , including glutamate , did not show marked alteration , the expression of the glutamatergic signaling pathway such as N - methyl - D - aspartate receptors , a - amino - 3 - hydroxy - 5 - methylisoxazole - 4 - propionic acid receptor , calmodulin , Ca ( 2 + ) / calmodulin - dependent protein kinases - II and cyclic adenosine monophosphate responsive element binding protein , was significantly reduced by TBT exposure , which indicated that central nerve activities were in a state of depression , thus affecting the predatory activities of the fish .
