Abstract

The effects of a single intraperitoneal administration of lithium, a drug used to prevent the recurrence of mania in bipolar disorders, were determined in the rat by studying changes in: (i) the wake-sleep cycle; (ii) autonomic parameters (hypothalamic and tail temperature, heart rate); (iii) the capacity to accumulate cAMP and IP(3) in the preoptic-anterior hypothalamic region (PO-AH) and in the cerebral cortex (CC) under an hypoxic stimulation at normal laboratory and at low ambient temperature (T(a)). In the immediate hours following the injection, lithium induced: (i) a significant reduction in REM sleep; (ii) a non-significant reduction in the delta power density of the EEG in NREM sleep; (iii) a significant decrease in the concentration of cAMP in PO-AH at normal laboratory T(a); (iv) a significant increase of IP(3) concentration in CC following exposure to low T(a). The earliest and most sensitive effects of lithium appear to be those concerning sleep. These changes are concomitant with biochemical effects that, in spite of a systemic administration of the substance, may be differentiated according to the second messenger involved, the brain region and the ambient condition.

Abstract

Serotonin [5-hydroxytryptamine (5-HT)] plays an inhibitory role in rapid-eye-movement (REM) sleep although the exact mechanism(s) and site(s) of action are not known. It is commonly assumed that 5-HT exerts its influence on REM sleep via input from the dorsal raphe nucleus (DRN) directly onto cholinergic neurons involved in the generation of REM sleep. 5-HT 2 receptor sites have been found on cholinergic neurons in the laterodorsal tegmental nucleus (LDT) and pedunculopontine tegmental nucleus (PPT). We locally microinjected the 5-HT 2 agonist DOI ((±)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane HCl) and the 5-HT 2 antagonist, ketanserin, in LDT in rats to determine whether these receptor sites are involved in the regulation of behavioral states. DOI and ketanserin primarily affected REM sleep, by significantly decreasing or increasing, respectively, the number, but not the duration, of REM sleep episodes. DOI specifically decreased the occurrence of clusters of REM sleep episodes appearing at intervals less than or equal to 3 min (sequential episodes) without affecting single episodes separated by more than 3 min. An opposite effect of ketanserin on REM sleep clusters, although not statistically significant, was observed.
