This study tested the hypothesis that increased activity in the pupilloconstrictor nucleus by the addition of ambient light and by the administration of fentanyl, sufficient to block pupillary reflex dilation, constricts the pupil of anesthetized patients. ⋯ This study does not support the hypothesis that opioid effects on the human pupil are brought about by a direct excitatory action on the pupilloconstrictor nucleus.

To examine the neurologic and neurophysiologic findings and neurologic symptoms in 12 women with Fabry disease and to study the relationship between the subjective symptoms and the findings on the various tests done. ⋯ While the clinical diagnosis of small-fiber neuropathy is difficult, the diagnostic yield can be increased using a combination of thermal QST and IENFD measurements.

To test if motor imagery prevents the rest-induced suppression of anterior horn cell excitability. ⋯ This finding documents the importance of central drive for spinal excitability, which affects F-wave studies of a paretic muscle.
