The dynamics of asymmetry of slow EEG waves are interpreted as a reflection of the activity of the slow regulating system which provides a global control of the levels of activity of the brain.doi:10.1016/0028-3932(66)90030-3E.Yu. Artemieva...
or EEG scan, identifies the stages of sleep. Other determining factors include breathing rate, heartbeat, muscle activity, how easily you can be awoken, and eye rolling or REM. These are compared to your waking activity when you emit beta waves with high frequency and low amplitude or intensi...
EEG signals are recorded from the scalp and then converted into commands that can be used to control a cursor, type words, or move a robotic arm. What is the BCI system? The BCI system is a set of hardware and software tools that allow people to communicate with a computer using their...
This scale invariant, self-similar property is used to describe the growth of trees, the formation of mountains, the branching of blood vessels and the crashing of ocean waves. Fractals, as noted by Benoit Mandelbrot (a pioneer in the field of fractal geometry), "are present everywhere." ...
EEG-ECG MI, besides clearly discriminating patients in an MCS − and +, significantly differed between lesioned areas (sides) in a subgroup of unilateral hemorrhagic patients. Crucially, such an accessible and non-invasive measure of residual consciousness signs was robust across electrodes and ...
participants were hooked up to an electroencephalograph, or EEG, that monitored brain waves while they took a reading test on word-figures they had already learned. Following the letter-sound style of training, participants were also tested on their ability to read new words composed of the sam...
The EEG (Electroencephalogram) is a representative signal containing information about the condition of the brain. The shape of the wave may contain useful information about the state of the brain. However, the human observer can not directly monitor these subtle details. Besides, since bio-signals...
Although several types of hypnotic state monitors are now available,1 2 there is no monitor measuring haemodynamic responsiveness to noxious stimulation during general anaesthesia. The EEG-based hypnotic state monitors do not provide parameters predictive of haemodynamic reaction or movement,3 although the...
Fig. 2. EEG of patients 11 at the age of 14 showing diffuse spike and waves discharges. No patients had evident epileptogenic lesions on brain MRI. Two patients presented with a mild diffuse cortical and subcortical atrophy (Patients 3 and 4), two exhibited cortical atrophy in the frontal ar...
Non-invasive measurement of uterine activity using electrohysterogram (EHG) surface electrodes has been attempted to monitor uterine contraction. This study aimed to computationally compare the performance of acquiring EHG signals using monopolar electrode and three types of Laplacian concentric ring electro...
