  • Title: [Histofluorescence study of epiphyseal monoamines in the garden dormouse (Eliomys quercinus L.) during various experimental conditions in hibernation period (author's transl)].
    Author: Cordonnier JL, Roux M.
    Journal: Ann Endocrinol (Paris); 1978; 39(5):403-10. PubMed ID: 570371.
    Abstract:
    During the hibernation period, the epiphyseal catecholamine charge is well detected in the garden dormouse; it appears more important in darkened animals at 22 degrees C and much less in animals under continuous lighting. Serotoninergic elements have only been shown in animals living under complete darkness. An important catecholaminergic and indolaminergic charge appears in sexually-hypoactive-animals; during ovarian activation after illumination a diminution (of this charge) is observed. In this species, an inverse relation exists between the importance of epiphyseal monoaminergic metabolism and the hypothalamic gonadostimulating catecholamine discharge.
