How does conscious perception evolve following stimulus presentation? The idea that
perception relies on discrete processing epochs has been often considered, but never widely …

Brain function involves oscillations at various frequencies. This could imply that perception
and cognition operate periodically, as a succession of cycles mirroring the underlying …

Determining the moment at which a visual recognition process is completed, or the order in
which various processes come into play, are fundamental steps in any attempt to understand …

Oscillations are ubiquitous in electrical recordings of brain activity. While the amplitude of
ongoing oscillatory activity is known to correlate with various aspects of perception, the …

What can we see when we do not pay attention? It is well known that we can be “blind” even
to major aspects of natural scenes when we attend elsewhere. The only tasks that do not …

… The result was that median reaction times were about 100 msec shorter (VanRullen &
Thorpe, in press). Despite this, the latency of the onset of the differential response at 150 msec …

Many behavioral responses are completed too quickly for the underlying sensory processes
to rely on estimation of neural firing rates over extended time windows. Theoretically, first-…

… On the basis of modeling of human psychometric functions in a signal detection task,
VanRullen et al. (8) recently proposed that attention could sample information at a rate of …

… The refractory period Ref acts as a constraint on the observed firing rate R, so that R cannot
… Hz (ie MaxF/2), that is, an observed firing rate R greater than 166 Hz when Ref = 5 ms (in our …

Increasing evidence suggests that attention can concurrently select multiple locations; yet it
is not clear whether this ability relies on continuous allocation of attention to the different …
