Abstract
The electrolytic lesions of Raphe or Locus coeruleus (I = 1-1,5 mA, 20 sec, with a change in polarity) produce a destabilization in the circ adian rhythms of the active searching behaviour (tested in the ''open field'') in rats kept under conditions of natural illumination in the period of the winter or summer solstice. The daily or circadian compon ents are substituted, respectively, for the ultra- or infradian rhythm s. If the animals are kept for 10 days under 24-h light or dark condit ions, the serotoninergic or noradrenergic deficit delays the formation of free-running rhythms.
