Strain differences in catecholamine content of pigeon brains.
Concentrations of dopamine, noradrenaline and DOPAC were measured in 6 regions of telencephalon and in the cerebellar cortex of adult white Carneaux, and mixed breed pigeons of either sex. In both groups the regional differences in the amount of dopamine replicated the pattern we published earlier. The absolute values, however, differed in these groups: in all telencephalic regions the amount of dopamine was lower in the Carneaux strain than in the mixed breed specimens; in 4 of these regions the difference was statistically significant. A similar tendency was observed in the noradrenaline concentration but the difference was significant only in two telencephalic samples and the cerebellum. The concentration of DOPAC was significantly smaller in two telencephalic regions of the Carneaux pigeons.
