Chicken suprachiasmatic nuclei: I. Efferent and afferent connections

Abstract: The avian circadian system is composed of multiple inputs, oscillators and outputs. Among its oscillators are the pineal gland, retinae and a hypothalamic structure assumed to be homologous to the mammalian suprachiasmatic nucleus (SCN). Two structures have been suggested as this homolog-the medial SCN (mSCN) and the visual SCN (vSCN). The present study employed biotin dextran amine (BDA) and cholera toxin B subunit (CTB) as anterograde and retrograde tracers to investigate the connectivity of the mSCN and vSC… Show more

“…While this structure has been referred to in the literature by a variety of designations (cf. Cantwell and Cassone, 2006), we will refer to this structure as the medial suprachiasmatic nucleus (mSCN), as indicated by Kuenzel and Masson (1988). Some studies have reported retinal afferents in the mSCN, but the label is weak (Hartwig, 1974;Oliver et al, 1978;Cantwell and Cassone, 2006) or undocumented with photomicrographs (Ebihara and Kawamura, 1981).…”

“…Jądro nadskrzyżowaniowe SCN W przeciwieństwie do ssaków, które posiadają jedno parzyste jądro SCN w podwzgórzu, u ptaków wystę-pują dwie pary jąder: mSCN oraz vSCN (11,12,57,99). Jądro mSCN znajduje się blisko kąta zachyłka przedwzrokowego III komory mózgu.…”

“…Jest większą i dłuższą strukturą niż mSCN. Udowodniono, że vSCN jest podstawowym odbiorcą bodźców świetlnych z siatkówki, co wykazano dotychczas u turkawki, wróbla, gołębia, kaczki i kury (11,12). Jądro mSCN otrzymuje bardzo nieliczną ilość włókien nerwowych bezpośrednio z siatkówki.…”
