Concentrations of estradiol in ewe cerebrospinal fluid are modulated by photoperiod through pineal-dependent mechanisms (2006)

Thiery, J.C., Lomet, D., Shumacher, M., Liere, P., Tricoire, H., Locatelli, A., ...

In the ewe, seasonal anestrus results from an increased responsiveness of the hypothalamus to the negative feedback of estradiol (E2) on the gonadotropic axis under long-day conditions. However, this...

Access of dopamine to the median eminence and brain throughout local vascular pathways in sheep (2004)

Skipor, J., Wasowska, B., Picard, S., Thiery, J.C.

In female sheep, estradiol-dependent dopaminergic inhibition exerted by the A15 nucleus during long days (LD) results in a blockade of reproductive activity. This effect could involve the GnRH cell...

Neuroendocrine interactions and seasonality (2002)

Thiery, J.C., Chemineau, P., Hernandez, X., Migaud, M., Malpaux, B.

Abstract Sheep in temperate latitudes are seasonal breeders. Of the different seasonal cues, photoperiod is the most reliable parameter and is used by animals as an indication of the time of the year...
