The pulsatile secretion of the hypophyseal luteinizing hormone (LH) is induced by the pulsatile secretion of the hypothalamic neurons secreting gonadotrophin-releasing hormone (GnRH). Seasonal variations in the pulsatility of LH were studied in the a

From 1984 to 1989, five populations of the Nile grass rat, Arvicanthis niloticus solatus, living in five different habitats of the Sahelian region were studied in northern Burkina Faso (Oursi, 14°N). The following were investigated: (i) seasonal var

Seasonal variations in the immunoreactivity of vasopressinergic perikarya in the paraventricular (PVN), supraoptic (SON) and suprachiasmatic nuclei (SCN), and in the labelling of vasopressinergic fibres in the internal zone of the median eminence wer

The strict photoperiodic dependence of gonadotropic function observed in mink provides an excellent physiological model for studying the activity of GnRH hypothalamic neurons. In mink, exposure to more than 10 h light inhibits the activity of this ne

The cellular localization of GnRH messenger RNA (mRNA) in the rat and the mink hypothalamus has been examined using a newly developed highly sensitive non-radioactive in situ hybridization procedure. Synthetic oligonucleotides labeled by addition of

The effects of superior cervical ganglionectomy on testicular function (testis volume and plasma testosterone levels) and the immunocytochemical activity of the GnRH hypothalamic system were studied in the mink, a short-day breeder. Animals reared in

The present study of the circadian rhythm of locomotor activity during the summer in minks reared in a natural photoperiod showed that under laboratory conditions, this species has an essentially nocturnal behavior. But the relatively extensive activ

This study was designed to examine possible relationships between the photoperiodic regulation of prolactin secretion and the activity of dopaminergic and GABAergic neurons projecting to the external layer of the median eminence. The study was carrie

The relationship between the photic stimulation of the c-fos gene product in cells of the suprachiasmatic nuclei and the photoperiodic control of testicular activity were examined in mink. Mink were kept in a short photoperiod (control, LD4:20), or i
