To determine whether the photoperiodic responses of reproductive and prolactin (PRL) rhythms in the ewe requires an intact suprachiasmatic nucleus (SCN) driving the pineal rhythm of melatonin secretion, four groups of ovary-intact ewes over a 6-year period were subjected to bilateral (n = 40) or sham lesions (n = 15) of the SCN. Animals were exposed to an(More)
Hippocampal high-frequency electrical stimulation (HFS) shows long-term efficiency in some pharmacoresistant temporal lobe epilepsy patients. However, the success of the procedure varies from patient to patient and neither neurologists nor neurosurgeons are currently unable to pre-operatively predict which patients will respond to the stimulation. Just like(More)
The objective of this study was to determine whether two photoperiod regimens that induce anestrus in the ewe-short-day photorefractoriness (SDPR) and long-day photosuppression (LDPS)--act by different neuronal mechanisms. In separate experiments, ovary-intact (INTACT), ovariectomized (OVX), and ovariectomized estradiol-treated (OVX + E) ewes were subjected(More)
This paper reports a case of surgical removal of a left-hemisphere arteriovenous malformation (AVM) in a left-handed adult without subsequent speech or language deficit. Preoperative intracarotid amobarbital testing indicated right-hemisphere language dominance. Our patient demonstrated no language involvement prior to or following surgery. We speculate the(More)
