objective: electroencephalogram is a reliable reflection of many physiological factors modulating the brain. the bispectrum is very useful for analyzing non-gaussian signals such as eeg, and detecting the quadratic phase coupling between distinct frequency components in eeg signals.the main aim of this study was to test the existence of nonlinear phase coupling within the eeg signals in a certa...

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 ...

60-year-old woman was treated for a brain metastasis. the patient received intensity-modulated radiation therapy (sib-imrt) dose of 30 gy for the whole brain and 40 gy delivered simultaneously to individual brain metastases in 10 fractions. the present report investigated the influence of applied novel prepared treatment plan, among others the fractionation protocol on the electroencephalogram ...

serotonin is believed as an important factor in brain function. the role of serotonin in cerebral psycho-patho-physiology has already been well established. however, the function of serotonin antagonist in anesthetized subjects under hyperthermia has not been studied properly. methods: experiments were performed in three groups of urethane-anesthetized rats, such as: (i) control group, (ii) who...

-Electroencephalography is the simple method of recording and measuring electrical activity of brain. This brain signal is amplified and resulting in electroencephalogram (EEG). EEG is non-invasive tool used in monitoring brain activities and diagnosis of many neurological disorder. The main challenge of EEG is the small signal amplitude and its sensitivity to noise because of which it demands ...

Continuous four hours EEG (electroencephalogram) recordings and its power spectrum analysis using fast fourier transform (FFT) in urethane anesthetized male Charles Foster rats were performed in two groups: open brain injury and p-CPA (para-Chlorophenylalanine) pretreated before brain injury, respectively, and compared with the EEG power spectrum of control rats. The EEG power spectrum analysis...

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...

The Electroencephalogram (EEG) is a biological signal that represents the electrical activity of the brain and is the main resource of information for studying neurological disorders. Corruption of EEG signal is caused by occurrence of various artifacts like line interference, electroculogram, electrocardiogram and muscle activity [3]. These artifacts resources increase the difficulty in analyz...

We report a case of hypermotor seizure activity. The patient presented behavioural changes with previous reports normal electroencephalogram (EEG). A prolonged video EEG this showed rare epileptic abnormalities over the left frontocentral region, which ruled out conversion disorder diagnosis. Management using Antiepileptics proved beneficial in case.
