Cerebrospinal fluid amino acid and monoamine metabolite levels of Papio papio: correlation with photosensitivity.
Several putative neurotransmitter amino acids and monoamine metabolites were measured in the cerebrospinal fluid of spontaneously photosensitive baboons (Papio papio) at different periods with varying degrees of photosensitivity in the same animals. At maximum photosensitivity the inhibitory amino acids gamma-aminobutyric acid and taurine were lower, and those of asparagine (metabolite of the excitatory amino acid aspartate) were higher, than when the animals were not photosensitive. Thus a decreased inhibition and perhaps increased excitation correlates with the level of photosensitivity.
