ATTENTIONAL DYNAMICS AT MULTIPLE TIME SCALES
We describe the dynamics of attentional signals from the range of several cycles per seconds to few cycles per hour and how this impacts behavioral performance.

MULTIPLEXING OF ATTENTION IN NEURONAL POPULATIONS
We describe the different information encoded in the prefrontal cortex together with attention, including task information, time information and states of distractability.

REAL-TIME DECODING OF ATTENTION
We use machine learning methods in order to track, in real-time spatial attention and sustained attention information from both invasive (multiunit activity, local field potentials) and non-invasive (fMRI) signals. These approaches are used in order to develop cognitive brain-machine interfaces.
