During the course of study on alteration in EEG pattern produced by changing ventilation, we noticed spontaneous EEG fluctuation in which two types of activities alternated at regular intervals in about half the series of experiments. Cortical and subcortical electrical activity as well as phrenic nerve volley and blood pressure was recorded in curarized cats under artificial respiration. The p...

Electroencephalogram (EEG) merupakan salah satu biomedical sensor yang mampu membaca gelombang otak . Sama halnya dengan lainnya (EMG/ECG), ini dikembangkan lebih lanjut diberbagai bidang satunya dibidang robotika. Penelitian menghasilkan sebuah sistim mekatronika untuk menggunakan electroencephalogram (EEG). Hasil dari sinyal ditangkap kemudian diolah menjadi suatu atensi digunakan mengetahui ...

PURPOSE To evaluate the value of a new multi-stage surgical procedure using bilateral intracranial electroencephalogram (iEEG) prior and post complete corpus callosotomy (CC) for epileptogenic focus localization. METHOD Thirty patients with drug-resistant epilepsy underwent bilateral iEEG monitoring to localize epileptogenic focus for surgical treatment. Among them, bisynchronous epileptogeni...

this paper describes the system design of a portable and economical mu rhythm based brain computer interface which employs cypress semiconductors programmable system on chip (psoc). by carrying out essential processing on the psoc, the use of an extra computer is eliminated, resulting in considerable cost savings. microsoft visual studio 2005 and psoc designer 5.01 are employed in developing th...

the recent literatures indicate that central nervous system (cns) is highly vulnerable to systemic hyperthermia induced by whole body heating on conscious animals. in the present study, cerebral electrical activity or eeg (electroencephalogram) following exposure to high environmental heat has been studied in moving rats. rats were divided into three group (i) acute heat stress-subjected to a s...

A two-compartment fusion system designed to reduce high rates of false alarm (FAR) in single channel monitoring systems was tested with physiological data from pilots exposed to high +Gz forces on a human centrifuge. The first compartment expands input signals into time-frequency domain, where transient changes are captured by wavelet coefficients in frequency ranges of interest. The second com...

Introduction In October 1996 the Food and Drug Administration approved the use of a new monitoring device of anesthetic effect that integrates various electroencephalogram (EEG) descriptors into a single dimensionless, empirically calibrated number, the Bispectral Index (BIS, Aspect Medical Systems, Natick, MA).1 The BIS monitor is the latest innovation in the quest for a reliable monitoring de...
