BACKGROUND Computer-assisted learning (CAL) offers a number of potential advantages for surgical technical skills teaching. The purpose of this study was to evaluate the impact of individualized external feedback on surgical skill acquisition when a CAL package is used for instruction. METHODS Freshman and sophomore students participated in a 1-hour CAL(More)
Electroconvulsive therapy (ECT) is remarkably effective in severe major depressive disorder (MDD). Growing evidence has accumulated for brain structural and functional changes in response to ECT, primarily within cortico-limbic regions that have been considered in current neurobiological models of MDD. Despite increasing evidence for important cerebellar(More)
We report a magnetotransport study of the termination of the spin-resolved integer quantum Hall effect by controlled disorder in a gated GaAs/Al x GaAs 1−x heterostructure. We have found that, for a given N th Landau level, the difference in filling factors of a pair of spin-split resistivity peaks δν N = |ν N ↑-ν N ↓ | changes rapidly from one to zero near(More)
