Timing is everything: scientists control rapid re-wiring of brain circuits using patterned visual stimulation
In a new study, published in this week’s issue of the journal Science, researchers show for the first time how the brain re-wires and fine-tunes its connections differently depending on the relative timing of sensory stimuli. In most neuroscience textbooks today, there is a widely held model that explains how nerve circuits might refine their connectivity based on patterned firing of brain cells, but it has not previously been directly observed in real time.

Our invited speaker's return from the high Arctic, where he was doing reseach, has been delayed due to bad weather. So we are cancelling this AstroNight.
We will try to reschedule him for an upcoming AstroNight
Dr. Guy Rouleau, Director of the Montreal Neurological Institute and Hospital -The Neuro, at McGill University and McGill University Health Centre, is being awarded the Prix d’excellence 2014 by the Collège des médecins du Québec, for his outstanding contributions to neurogenetics and medicine. Dr. Rouleau accepts the award today at a ceremony at the Chateau Frontenac in Quebec City.

As part of the Quebec-wide event 24 Hours Of Science (http://www.science24heures.com/), AstroMcGill is organizing two events. On Friday, May 9th (starting at 8pm) another new "AstroKids Night" will feature many hands-on activities, and observations of the night-sky. On Saturday, May 10th (starting at 10am) the event will continue with the same activities, and observations of the Sun.
These activities will be offered in french and english. This event is free of charge and no reservation is required.
In less than a decade, resting-state functional MRI has become an important paradigm for studying the network properties of brain function, providing convincing evidence for the Hebbian concept of neuronal assemblies that act in coherence, and constitute the functional organization of the brain.
On Friday, May 2, the Centre for Research on Brain, Language and Music (CRBLM) will host a one-day symposium, our second annual meeting, to explore the overlap and divergence between language and music in sensorimotor integration. A substantial amount of work in speech demonstrates a close functional relationship between neural systems responsible for motor control and those responsible for sensory processing. A remarkable parallel exists in music performance, where there is good evidence for similar functional relationships between motor execution and perception.
Intonation, rhythm, and the melody of language are among the first aspects of speech that infants attend to and produce themselves. What is more, in order to grasp the full literal and social meaning of an utterance, syntactic and semantic information is not enough - intonation and prosodic modulations must be taken into account. Yet, prosodic features are among the last to be mastered by both L1 and (adult) L2 learners both in utterance production and comprehension.
