Research

The research in the lab focuses on three major areas: examining the effects of low-intensity TMS, employing psychophysics to understand functional effects of TMS and developing new procedures to help with measurements of TMS thresholds.

Can TMS improve the detection of visual stimuli? TMS is usually employed to impair visual perception. Here we demonstrate improvement in visual detection using TMS pulse applied below the phosphene threshold.

Should we characterise the functional effect of TMS as noise induction or signal suppression? Data from two studies using either static or moving stimuli are better explained as signal suppression than as noise induction in the brain.

We have implemented an adaptive staircase procedure to rapidly and accurately estimate phosphene thresholds. The procedure is implemented in Matlab and is available for download.
