Detecting brain waves communication"
30/08/2010 00:00:00 BRT

Tort et al present a powerful framework for quantifying the level of coupling among simultaneous brain oscillations, which will help elucidating the importance of brain waves communication in cognitive processes."

Neocortex and vocal production in marmosets"
23/09/2010 00:00:00 BRT

Our data provide direct evidence that the ventrolateral prefrontal cortex, a key region for speech control in humans, is also activated during vocal production in a non-human New World primate."

Spike Avalanches Exhibit Universal Dynamics across the Sleep-Wake Cycle."
30/11/2010 00:00:00 BRT

Stem cells to neurons: Independent of local niche"
22/03/2011 00:00:00 BRT

Adult neural stem cells (NSCs) could be used to treat nervous system disorders, but does their specification require a local niche? Using adult mouse NSCs, Costa and colleagues show that progression from stem cell to neuron is cell-intrinsic and independent of the local niche."

Motion representation in V1 is mediated by transcortical feedback"
19/04/2011 00:00:00 BRT

Global features of the visual scenery are fed back to lower visual processing units to facilitate the integration of local cues into a global construct."
