Experimental determination of human peripheral nerve stimulation thresholds in a 3-axis planar gradient system.

30 Aug 2009 In MRI, strong, rapidly switched gradient fields are desirable because they can be used to reduce imaging time, obtain images with better resolution, or improve image signal-to-noise ratios. Improvements in gradient strength can be made by either ... Read more...

Automated threshold detection for auditory brainstem responses: comparison with visual estimation in a stem cell transplantation study.

24 Aug 2009 BACKGROUND: Auditory brainstem responses (ABRs) are used to study auditory acuity in animal-based medical research. ABRs are evoked by acoustic stimuli, and consist of an electrical signal resulting from summated activity in the auditory nerve and ... Read more...

Estimating the difference limen in 2AFC tasks: pitfalls and improved estimators.

30 Jul 2009 Discrimination performance is often assessed by measuring the difference limen (DL; or just noticeable difference) in a two-alternative forced choice (2AFC) task. Here, we show that the DL estimated from 2AFC percentage-correct data is likely to ... Read more...
