Abstract
The osmotic stimulation which is able to change the behavioral state of the animal are most effective during rainy weather while they are less effective during dry weather conditions. In isolated CNS preparations from aestivated animals the highest firing activity and serotonin sensitivity of the serotonergic (RPas) heart modulator neurons are recorded during rainy weather and the lowest parameters are observed in dry conditions. In aestivated animals the serotonin (5HT) content in both the CNS and the foot is higher than the dopamine (DA) content during rainy weather, while in dry weather the DA level is higher than the 5HT. The inactivation-reactivation process is accompanied by decreasing both the DA and 5HT levels in the CNS and increasing them in the peripheral organs. Our results suggest that aestivated animals adapt to (favorable and unfavorable) environmental conditions by modulating their central arousal state through changing the levels and distribution of monoamines (5HT, DA) in their body.
