Spatiotemporal distortions of visual perception at the time of saccades.

19 Oct 2009 Both space and time are grossly distorted during saccades. Here we show that the two distortions are strongly linked, and that both could be a consequence of the transient remapping mechanisms that affect visual neurons perisaccadically. We measured ... Read more...

Perceptual distortion in homonymous paracentral scotomas.

27 Feb 2009 BACKGROUND: Cortical remapping after peripheral or central visual deafferentation alters visual perception, but it is unclear whether such a phenomenon impinges on areas remote from a scotoma. To investigate this question, we studied variations of ... Read more...

Attention, automaticity, and awareness in synesthesia.

27 Feb 2009 The phenomenon of synesthesia has occupied the thoughts of philosophers and artists for decades. With the advent modern behavioral and brain imaging techniques, scientific research on synesthesia has also moved into the mainstream of thought. Here I ... Read more...
