We demonstrate a form of long-term depression (LTD) in the perirhinal cortex that relies on interaction between different glutamate receptors. Group II metabotropic glutamate (mGlu) receptors facilitated group I mGlu receptor-mediated increases in intracellular calcium. This facilitation plus NMDA receptor activation may be necessary for induction of LTD at(More)
The developmental mechanisms through which the cerebral cortex increased in size and complexity during primate evolution are essentially unknown. To uncover genetic networks active in the developing cerebral cortex, we combined three-dimensional reconstruction of human fetal brains at midgestation and whole genome expression profiling. This novel approach(More)
Topographic representation of visual fields from the retina to the brain is a central feature of vision. The development of retinotopic maps has been studied extensively in model organisms and is thought to be controlled in part by molecular labels, including ephrin/Eph axon guidance molecules, displayed in complementary gradients across the retina and its(More)
BACKGROUND There is a dearth of information on the clinicopathological differences, including the molecular subtypes, of breast carcinomas from immigrant Arab women in Europe. Therefore, the aim of our study was to examine and compare these features in immigrant Arab/Moroccan patients with those of European women. METHODS Included in this study were 441(More)
REMERCIEMENTS J'aimerais exprimer ici toute l'admiration et l'affection que j'éprouve pour le Professeur Bertrand DOUSSET qui, tout en me transmettant son expérience chirurgicale, m'a progressivement conduite sur la voie de la recherche. C'est ainsi que j'ai découvert un autre univers, celui des sciences. Le Professeur Frédéric BATTEUX m'y a chaleureusement(More)
Endometriosis, the hormone-dependent extrauterine dissemination of endometrial tissue outside the uterus, affects 5-15% of women of reproductive age. Pathogenesis remains poorly understood as well as the estrogen production by endometriotic tissue yielding autocrine growth. Estrogens (E2) are normally produced by the ovaries. We investigated whether(More)
