“…The retinal projections to the SCN in the marmoset have been described in previous studies from our laboratory (Costa and Britto, 1997;Costa et al, 1998). Our results confirm the original descriptions of the retinal input to the SCN (Hendrickson et al, 1972;Moore and Lenn, 1972;Moore, 1973).…”

“…The CTS of mammals has three main components: an afferent pathway (also called the primary synchronizing pathway, which receives information from the environment), a central clock responsible for generating circadian oscillations, and efferent pathways (through which the CTS communicates with behavioral and physiological effectors and through which the The dorsomedial subpopulation, which receives very few fibers from the RHT and GHT, produces vasopressin (VP) (Moore, 1993). This neurochemical characterization exhibits phylogenetic conservation, and these subpopulations are found in nearly all of the species studied (Cassone, Speh, Card, & Moore, 1988;Wang et al, 1997;Costa et al, 1998;Goel, Lee, & Smale, 1999;Smale & Boverhof, 1999).…”

All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, responsible for this process, is formed by connected neural structures. Pathways receive and transmit environmental cues to the central oscillator, the hypothalamic suprachiasmatic nucleus, which mediates physiological and behavioral alterations. The suprachiasmatic nucleus has three major inputs: the retinohypothalamic tract (a direct projection from the retina), the geniculohypothalamic tract (an indirect photic projection originating in the intergeniculate leaflet), and a dense serotonergic plexus from the raphe nuclei. The serotonergic pathway, a source of non-photic cues to the suprachiasmatic nucleus, modulates its activity. The importance of raphe nuclei in circadian rhythms, especially in photic responses, has been demonstrated in many studies. Serotonin is the raphe neurotransmitter that triggers phase shifts, inhibits light-induced phase-shifts, and plays a role in controlling the sleep-wake cycle. All data to date have demonstrated the importance of the raphe, through serotonergic afferents, in adjusting circadian rhythms and must therefore be considered a component of the circadian timing system. The aim of this paper is to review the literature addressing the involvement of serotonin in the modulation of circadian rhythm.

“…Células imunorreativas a CB também foram descritas nesta classe (Costa et al, 1998;Mai et al, 1991) Quanto aos neurônios imunorreativos à AVP (AVP IR) e VIP (VIP IR), em humanos, assim como em roedores, apresentam-se em porções topograficamente distintas do SCh, sendo a distribuição dos neurônios AVP IR médio dorsal e VIP IR ventral (Dai et al, 1997). Contrariamente, em outros primatas os neurônios VIP IR foram observados na porção dorsal (Costa et al, 1998), ou central do SCh (Moore, Speh, 2004).…”

“…Entretanto, ocorrem variações, como por exemplo, neurônios VIP IR na porção dorsal do núcleo no sagüi (Costa et al, 1998) e neurônios AVP IR localizados no contorno lateral do SCh no camundongo (Abrahamson, Moore, 2001). A divisão anátomo-funcional do SCh em porção ventrolateral e dorsomedial também é conhecida como core e shell (Card, Moore, 1991;Moore et al, 2002;Van den Pol, Tsujimoto, 1985).…”
