We studied the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) on seizure susceptibility in rats. rTMS of 1000 pulses at 0.5 Hz led to a prolonged latency for seizure development after an intraperitoneal injection of pentylenetetrazol. The rTMS effectively prevented the development of status epilepticus of(More)
OBJECTIVES To report follow-up studies of cerebellar stimulation in patients with acute cerebellar ataxia (ACA). METHODS We studied two patients with ACA. One patient also had decreased deep sensations in the feet due to combined diseases such as diabetic polyneuropathy and lumbosacral radiculopathies. We applied the technique of electrical stimulation(More)
OBJECTIVES To examine high frequency oscillations (HFOs) of somatosensory evoked potentials (SEPs) recorded directly from subdural electrodes to investigate the relationship between the primary somatosensory cortex and HFOs. METHODS SEPs were recorded directly from subdural electrodes previously implanted in 3 patients for clinical evaluation prior to(More)
Carpal tunnel syndrome (CTS), compression of the median nerve at the carpal tunnel of the wrist, is the most common of all entrapment syndromes. Diabetes, Rheumatoid arthritis, hypothyroidism and pregnancy are known to cause CTS. And certain occupations were been reported the risk factor of CTS. We report two patients with occupationally induced CTS, and(More)
Motor evoked potentials (MEPs) elicited by magnetic coil stimulation of motor cortex were studied at rest and during maximum voluntary muscle contraction in 20 normal subjects and 42 patients with motor disorders. MEP parameters employed in this study included: onset latency, amplitude, MEP/M wave amplitude ratio and background EMG/MEP area ratio. Maximum(More)
We report two patients with deafferentation pain secondary to central nervous system lesions who were evaluated by noninvasive magnetic coil stimulation of the motor cortex followed by electrical motor cortex stimulation with epidural electrode array implantation. Magnetic coil stimulation was very useful to estimate the effect of electrical stimulation.(More)
OBJECTIVE To elucidate whether area 44 of human frontal cortex is essential for the organization of voluntary hand movements or not, the authors examined effects of single transcranial magnetic stimulation (TMS) of human area 44 on voluntary hand movement and electromyography (EMG) activities in hand muscles. METHOD Surface EMG responses were recorded(More)
We examined the effects of conventional antiepileptic drugs (AEDs) on absence-like seizures in homozygous tremor rats (tm/tm) to determine if they corresponded pharmacologically to human absence seizures and absence-like seizures in spontaneously epileptic rats (SER: zi/zi, tm/tm) with both tonic convulsive and absence-like seizures. Cortical and(More)
We report a family with 16q-ADCA(16q 22.1 linked autosomal dominant cerebellar ataxia) coexisting with SCA8 repeat expansion. The brothers in this family presented with pyramidal signs, tremor, myoclonus and mental retardation in addition to cerebellar symptom in childhood. They showed both C-to-T substitution puratrophin-1 gene and an expanded allele of(More)
There is little evidence for multisession repetitive transcranial magnetic stimulation (rTMS) on pain relief in patients with neuropathic pain (NP), although single-session rTMS was suggested to provide transient pain relief in NP patients. We aimed to assess the efficacy and safety of 10 daily rTMS in NP patients. We conducted a randomized, double-blind,(More)
