Functional anatomy of the attentional modulation of time estimation

JT Coull, F Vidal, B Nazarian, F Macar - Science, 2004 - science.org
Attention modulates our subjective perception of time. The less we attend to an event's
duration, the shorter it seems to last. Attention to time or color stimulus attributes was modulated …

Error negativity on correct trials: a reexamination of available data

F Vidal, B Burle, M Bonnet, J Grapperon… - Biological …, 2003 - Elsevier
The error negativity, an EEG wave observed when subjects commit an error in a choice
reaction time (RT) task, is often considered as a sign of error detection. Recently, reports of Ne-…

The supplementary motor area in motor and sensory timing: evidence from slow brain potential changes

F Macar, F Vidal, L Casini - Experimental brain research, 1999 - Springer
The present study investigated the processing of durations on the order of seconds with
slow cortical potential changes. The question is whether trial-to-trial fluctuations in temporal …

[HTML][HTML] Spatial and temporal resolutions of EEG: Is it really black and white? A scalp current density view

…, C Roger, L Casini, T Hasbroucq, F Vidal - International Journal of …, 2015 - Elsevier
Among the different brain imaging techniques, electroencephalography (EEG) is classically
considered as having an excellent temporal resolution, but a poor spatial one. Here, we …

Principles and applications of computer graphics in medicine

FP Vidal, F Bello, KW Brodlie, NW John… - Computer Graphics …, 2006 - Wiley Online Library
The medical domain provides excellent opportunities for the application of computer graphics,
visualization and virtual environments, with the potential to help improve healthcare and …

Executive control in the Simon effect: an electromyographic and distributional analysis

B Burle, CA Possamaï, F Vidal, M Bonnet… - Psychological …, 2002 - Springer
Manual responses to lateralized stimuli are faster for spatially congruent stimulus-response
associations than for incongruent associations, even if the stimulus location is irrelevant. This …

Activation of the supplementary motor area and of attentional networks during temporal processing

…, M Bonnet, A Ferrara, V Pouthas, F Vidal… - Experimental Brain …, 2002 - Springer
This paper first provides a survey of the expanding brain imaging literature in the field of time
processing, showing that particular task features (discrete vs rhythmic, perceptual vs motor) …

Action monitoring and medial frontal cortex: leading role of supplementary motor area

…, C Liégeois-Chauvel, J Régis, P Chauvel, F Vidal - Science, 2014 - science.org
The capacity to evaluate the outcomes of our actions is fundamental for adapting and optimizing
behavior and depends on an action-monitoring system that assesses ongoing actions …

Sum-frequency generation spectroscopy of interfaces

F Vidal, A Tadjeddine - Reports on Progress in Physics, 2005 - iopscience.iop.org
This paper reviews aspects of nonlinear optical spectroscopy of interfaces. The emphasis is
put on second-order nonlinear optical techniques, such as sum-frequency generation (SFG), …

Physiological evidence for response inhibition in choice reaction time tasks

B Burle, F Vidal, C Tandonnet, T Hasbroucq - Brain and cognition, 2004 - Elsevier
Inhibition is a widely used notion proposed to account for data obtained in choice reaction
time (RT) tasks. However, this concept is weakly supported by empirical facts. In this paper, …
