Catecholamines in some hypothalamic and telencephalic nuclei of food deprived rats.

The influence of 48 h food deprivation on the levels of catecholamines was investigated in different hypothalamic and telencephalic nuclei of the rat brain. There were on changes in the levels of noradrenaline (NA) and dopamine (DA) in the lateral hypothalamic area, dorsomedial nucleus, medial preoptic area and in nucleus of diagonal band (septum). On the other hand we observed a statistically significant decrease of NA and DA in the ventromedial nucleus and the decrease of NA in the arcuate nucleus.
