Propagating waves of activity have been recorded in many species, in various brain states,
brain areas, and under various stimulation conditions. Here, we review the experimental …

In principle, cortico-cortical communication dynamics is simple: neurons in one cortical area
communicate by sending action potentials that release glutamate and excite their target …

Deep regions of the brain are not easily accessible to investigation at the mesoscale level in
awake animals or humans. We have recently developed a functional ultrasound (fUS) …

Voltage-sensitive dye imaging (VSDi) has revealed fundamental properties of neocortical
processing at macroscopic scales. Since for each pixel VSDi signals report the average …

Microsaccades are small rapid and involuntary eye movements that occur during fixation in
an apparently stochastic manner. They are known to be inhibited in response to sensory …

To efficiently drive many behaviors, sensory systems have to integrate the activity of large
neuronal populations within a limited time window. These populations need to rapidly …

Masking and crowding are major phenomena associated with contextual modulations, but
the relationship between them remains unclear. We have recently shown that crowding is …

The neuronal mechanisms underlying perceptual grouping of discrete, similarly oriented
elements are not well understood. To investigate this, we measured neural population …

Collinear facilitation is a common phenomenon in the fovea, but it has been recently
challenged at the human periphery. Since physiological studies show that facilitation is …

Columnar organization of orientation selectivity and clustered horizontal connections linking
orientation columns are two of the distinctive organizational features of primary visual cortex …
