- Abstract
- ABSTRACT
The most debated matter in electrophysiological
investigations of neural mechanisms governing atten
tional selection of visual information is the 'timing
of attentional modulation of processing in the visual
pathways. Indeed, because of their high temporal res-
olution (in the order of milliseconds), but their scarce
spatial resolution in localizing neural processing,
event-related potentials (ERPsj of the bmin have < on-
tributed predominantly to determining the time at
which a particular attentional manipulation affects
visual processing, and to providing evidence for the
debate on early versus late selection. After a review of
our own ERP studies and in vivo cellular, ERPs/ERFs,
and fMRI studies of other authors, we advance the
opinion that although modulation of spatial attention
processing might start after relatively longer latencies
and in extrastriate areas, feature-directed attention
affects striate cortical, if not subcortical, regions at a
very early time point. (literal)
