Discharge patterns of 63 neurons in the bed nucleus of the stria terminalis (BNST) were cross-correlated with inspiratory onsets of the respiratory cycle and the R wave of the cardiac cycle in seven unrestrained, drug-free cats during waking (AW), quiet sleep (QS) and rapid eye movement (REM) sleep. BNST neurons fired slowly, with half having rates of less(More)
Contingent negative variations (CNV) were recorded during the S1-S2 interval of two simple and one discriminative task at Fz, Cz and Pz of 12 physically-trained college athletes and 12 non-trained students. The reaction time to S2 was also measured. The whole mean CNV amplitude average over the 2 sec S1-S2 interval and the segmented CNV amplitudes of the(More)
Electromyographic artifacts are sometimes misinterpreted as epileptic discharges in scalp electroencephalograms (EEGs). In addition, the distribution of the epileptic discharges near the earlobe is often distorted by earlobe activation; therefore, these epileptic discharges may not be correctly diagnosed. Here, we report a case of palatal tremor in which(More)
Male rats with indwelling electrodes for electroencephalographic (EEG), electromyographic (EMG) and electrooculographic (EOG) recordings were exposed via inhalation to 900 ppm and 2700 ppm toluene vapor continuously for a 8-h period or repeatedly for 3 weeks at a rate of 8 h/day and 5 days/week. Rats exposed to a clean air-stream under the same exposure(More)
BACKGROUND Attention deficit disorder/hyperactivity disorder (ADHD) is a pathological condition that is not fully understood. In this study, we investigated electroencephalographic (EEG) power differences between children with ADHD and healthy control children. METHODS EEGs were recorded as part of routine medical care received by 80 children with ADHD(More)
A 12-year-old girl presented with talipes equinus of both legs, attenuation of upper and lower limb tendon reflexes, thermal hyperalgesia, and reduction of vibratory sensation. On clinical examination, muscle twitches of fingers of both hands, as well as the abductor halluces and the dorsal interossei muscles of the right foot were observed. Nerve(More)
The ability to fix the eyes on a target, visual fixation, is important for the maintenance of equilibrium. The visual suppression (VS) test is one method of measuring the function of visual fixation. The test records caloric nystagmus by electrooculography, and the maximum slow phase velocity of caloric nystagmus in darkness is compared with the slow phase(More)
BACKGROUND To differentiate the features of electroencephalography (EEG) after status epileptics in febrile children with final diagnosis of either febrile seizure (FS) or acute encephalopathy for an early diagnosis. METHODS We retrospectively collected data from 68 children who had status epilepticus and for whom EEGs were recorded within 120 h. These(More)
