The purpose of this study was to determine the intra-rater reliability of motor evoked potentials (MEP) obtained through transcranial magnetic stimulation (TMS). TMS was applied over the primary motor cortex of 16 healthy subjects. Motor thresholds, MEP latencies, and amplitudes were recorded from the contralateral upper limb on 6 occasions over 15 days. An intraclass correlation coefficient (ICC 2,1) was used to estimate reliability. The ICCs ranged from 0.60 to 0.92 for all MEP measures except amplitude (ICC = 0.01 to 0.34). MEPs obtained with the TMS technique described are generally reliable, although MEP amplitudes demonstrated less consistency.

MEP abnormalities among acutely concussed collegiate athletes provide direct electrophysiologic evidence for the immediate effects of concussion.

We present a method for mending strategies for GR(1) specifications. Given the addition or removal of edges from the game graph describing a problem (essentially transition rules in a GR(1) specification), we apply a µ-calculus formula to a neighborhood of states to obtain a "local strategy" that navigates around the invalidated parts of an original synthesized strategy. Our method may thus avoid global resynthesis while recovering correctness with respect to the new specification. We illustrate the results both in simulation and on physical hardware for a planar robot surveillance task.

Variability in MEP latencies between genders was due to differences in upper extremity length. Adjusting MEP latencies to upper limb length is recommended for more accurate comparison and meaningful interpretation between subjects. Hand dominance and gender do not significantly influence motor thresholds, MEP amplitude, or CMCT.
