My objective of this study was to find evidence of chaotic itinerancy in human brains by means of noninvasive recording of the electroencephalogram (EEG) from the scalp of normal subjects. My premise was that chaotic itinerancy occurs in sequences of cortical states marked by state transitions that appear as temporal discontinuities in neural activity patterns. I based my study on unprecedented...
A study of vertigo in 50 children showed that a careful neurological examination should be performed for all patients. A detailed family and personal history to find possible episodes of loss of consciousness or seizures should be obtained; 13 children with vertiginous seizures had a positive family history for seizures and 5 had febrile seizures in infancy. Electroencephalograms should be obta...
BACKGROUND This study investigated the clinical and biological concomitants of electroencephalogram power abnormalities in schizophrenia. METHODS We examined the power characteristics of resting electroencephalograms in 112 schizophrenic patients. Also collected were measures of psychotic symptomatology, brain morphology, ocular motor functioning, electrodermal activity, and nailfold plexus v...
Recent advances in electrodes for noninvasive recording of electroencephalograms expand opportunities collecting such data for diagnosis of neurological disorders and brain-computer interfaces. Existing technologies, however, cannot be used effectively in continuous, uninterrupted modes for more than a few days due to irritation and irreversible degradation in the electrical and mechanical prop...
[Purpose] This study investigated how participation in a recreation program influences electroencephalogram changes in the demented elderly. [Subjects] Fourteen patients were included in the experimental group and 18 in the control group. [Methods] They had no regular exercise habits, and walked independently, and scored 11-23 points on the Mini-Mental State Examination, and thus had no apraxia...
Abstract Technology can translocate traditional art into interactive, immersive experiences. At the Asian Art Museum of San Francisco, authors transformed Tibetan Buddhist mandalas a 3D virtual reality mandala installation. Furthering this project, they externalized an analog meditative experience by recording electroencephalograms that dynamically modulated visual scene. The use neurofeedback ...
