Numerous studies have demonstrated that the power of ongoing alpha oscillations in the EEG is inversely related to neural excitability, as reflected in spike-firing rate, multi-unit activity, or the hemodynamic fMRI signal. Furthermore, alpha oscillations also affect behavioral performance in perceptual tasks. However, it is surprisingly unclear which latent perceptual or cognitive mechanisms mediate this effect. For example, an open question is whether neuronal excitability fluctuations induced by alpha oscillations affect an observer’s acuity or perceptual bias.

In the mammalian brain, sensory representations emerge from the activity of interconnected neurons in large cortical networks. Learning novel representations requires modifications in the

Pour la première fois, quatre grandes écoles ont décidé de faire Portes Ouvertes communes. Situées au coeur de Paris, l’École normale supérieure, l’ESPCI Paris, MINES ParisTech et Chimie ParisTech, toutes membres de l’Université PSL (Paris Sciences & Lettres), ouvriront leurs établissements le samedi 16 février de 13h à 18h. Leur volonté ? Donner aux étudiants l’envie d’intégrer leurs formations, qui couvrent un très large panel de disciplines, et qui offrent de nombreuses passerelles entre elles.

Human midbrain contains nuclei with critical functions for sensation and perception. In particular, the superior colliculus (SC) mediates eye and head movements, the allocation of attention, and multi-sensory integration that are all critical to visually guided behavior. Inferior colliculus (IC) plays a critical in auditory guided behavior. Both of these structures are small (<1 cm diameter) and divided functionally and cytoarchitecturally into multiple laminae.
