Acute carotid stenting in patients undergoing thrombectomy : a systematic review and meta-analysis
(BMJ Publishing Group, 2020-06-12)Background The benefit of acute carotid stenting compared with no acute stenting on clinical outcomes among patients with tandem lesions (TL) undergoing endovascular thrombectomy (EVT) remains unknown. Methods We conducted a a systematic review and ... -
Alternative Time Representation in Dopamine Models
(Springer Science + Business Media, 2009)Données originales publiées dans l'article: Rivest, F, Kalaska, J.F., Bengio, Y. (2009) Alternative time representation in dopamine models. Journal of Computational Neuroscience. doi:10.1007/s10827-009-0191-1 -
Bilateral connectivity in the brainstem respiratory networks of lampreys
(Wiley, 2011-11-18)This study examines the connectivity in the neural networks controlling respiration in the lampreys, a basal vertebrate. Previous studies have shown that the lamprey paratrigeminal respiratory group (pTRG) plays a crucial role in the generation of ... -
A brainstem neural substrate for stopping locomotion
(Society for Neuroscience, 2018-12-12)Locomotion occurs sporadically and needs to be started, maintained, and stopped. The neural substrate underlying the activation of locomotion is partly known, but little is known about mechanisms involved in termination of locomotion. ... -
Dopaminergic mechanisms underlying the expression of antipsychotic-induced dopamine supersensitivity in rats
(Elsevier, 2021-08-05)Antipsychotic treatment can produce a dopamine-supersensitive state, potentiating the response to dopamine receptor stimulation. In both schizophrenia patients and rats, this is linked to tolerance to ongoing antipsychotic treatment. In rodents, dopamine ... -
Incidence and prevalence of drug-resistant epilepsy : a systematic review and meta-analysis
(Lippincott, Williams & Wilkins, 2021-03-15)Objective To evaluate the incidence and prevalence of drug-resistant epilepsy (DRE) as well as its predictors and correlates, we conducted a systematic review and meta-analysis of observational studies. Methods Our protocol was registered with ... -
Metabotropic group II glutamate receptors in the basolateral amygdala mediate cue-triggered increases in incentive motivation
(Springer, 2021-07-05)Rationale: Reward-associated cues can trigger incentive motivation for reward and invigorate reward-seeking behaviour via Pavlovian-to-instrumental transfer (PIT). Glutamate signaling within the basolateral amygdala (BLA) modulates cue-triggered increases ... -
Non-contrast CT markers of intracerebral hematoma expansion : a reliability study
(Springer, 2022-03-29)Objectives: We evaluated whether clinicians agree in the detection of non-contrast CT markers of intracerebral hemorrhage (ICH) expansion. Methods: From our local dataset, we randomly sampled 60 patients diagnosed with spontaneous ICH. Fifteen ... -
Olfactory-induced locomotion in lampreys
(Springer, 2021-10-21)The olfactory system allows animals to navigate in their environment to feed, mate, and escape predators. It is well established that odorant exposure or electrical stimulation of the olfactory system induces stereotyped motor responses in fishes. ... -
Predicting early post-stroke aphasia outcome from initial aphasia severity
(Frontiers media, 2020-02-21)Background: The greatest degree of language recovery in post-stroke aphasia takes place within the first weeks. Aphasia severity and lesion measures have been shown to be good predictors of long-term outcomes. However, little is known about their ... -
Risk of cancer following an ischemic stroke in the Canadian longitudinal study on aging
(Cambridge University Press, 2021-03-26)Background: Stroke survivors may be at higher risk of incident cancer, although the magnitude and the period at risk remain unclear. We conducted a retrospective cohort study to compare the risk of cancer in stroke survivors to that of the general ... -
Sensory cutaneous papillae in the sea lamprey (Petromyzonmarinus L.) : I. Neuroanatomy and physiology
(Wiley, 2019-09-20)Molecules present in an animal's environment can indicate the presence of predators,food, or sexual partners and consequently, induce migratory, reproductive, foraging,or escape behaviors. Three sensory systems, the olfactory, gustatory, and ... -
Serotoninergic modulation of sensory transmission to brainstem reticulospinal cells
(Wiley, 2008-08-05)Sensory inputs are subjected to modulation by central neural networks involved in controlling movements. It has been shown that serotonin (5‐HT) modulates sensory transmission. This study examines in lampreys the effects of 5‐HT on sensory transmission ... -
Stroke mimics transported by emergency medical services to a comprehensive stroke center : the magnitude of the problem
(Elsevier, 2018-10)Background: Despite the use of validated prehospital stroke screens, stroke mimics are frequent among patients transported by Emergency Medical Services to the Emergency Department. We aimed to describe the frequency and characteristics of neurological ... -
