OBJECTIVE To determine whether cortical electrical stimulation can terminate bursts of epileptiform activity in humans, we used afterdischarges (ADs) as a model of epileptiform activity. METHODS Cortical stimulation was performed for clinical localization purposes using subdural electrodes implanted in patients undergoing preresection evaluations for(More)
A 42-year-old man presented with action-induced, stereotyped posturing of the left leg with task specificity following major traumatic brain injury less than a year earlier. Although adult onset primary leg dystonia is a recognised entity, our patient is unusual in that dystonia was an isolated abnormality without associated spasticity, was not preceded by(More)
Ocular flutter (OF) refers to occasional bursts of involuntary horizontal oscillation around the point of fixation, characterised by rapid horizontal repetitive oscillation without intersaccadic interval in electro-ocular recording. In spite of numerous reports of OF, there has been no previous report describing OF developed by simply looking at moving(More)
Anisotropic spin-orbit scattering of hot-electron spins in ferromagnets is examined by injecting a hot-electron current into the thin ferromagnetic base of a transistor and measuring the current attenuation as a function of the magnetization orientation. The transmission anisotropy is described by a simple model, from which we extract an effective(More)
A single dose of aconitine (0.6 mg/kg), the principal constituent of aconite, was administered intraperitoneally in order to evaluate its toxic effects on the visual system of a rabbit model. The typical pattern in which the alteration in the visual evoked potential occurred after an aconitine injection consisted of a delay in the onset and peak latency,(More)
