Contribution of deep brain sources on scalp EEG is still under debate. It is particularly true for mesial temporal sources which are deep with an infolded geometry. We analyzed simultaneous multi-scale EEG recordings (scalp and intracerebral) to delineate their contribution to scalp EEG. Interictal...
An EEG isa test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of...
In electroencephalography,electrodesare used to detect electrical activity in thebrain. The electrical activity detected by the electrodes is recorded and converted into a format that can be examined by a doctor. The most common use of an electroencephalogram (EEG) is to diagnoseepilepsy. Electroence...
In addition, an EEG can confirm brain death in a comatose patient. Electrodes in the form of small metal discs are placed on the patient’s scalp. The discs are attached to a machine that detects the patient’s brain waves and transforms them into information that can be interpreted by ...
Gesture recognition - Specialized device to detect different gestures, including facial expressions, reading lips, and sign language. Head-mounted pointer - A pointer can be mounted to a hat or band to track and control the mouse pointer. Joystick - A joystick next to the computer or on a wh...
[51] and can detect clear abnormality in case of peripheral field loss [50]. Although multifocal VEP technique can be a demanding test, it was shown to be possible in children from 5 years of age and might represent a promising objective test of children’s visual fields even before they ...
Eye-based measures are easily assessed in combination with other non-invasive neuroimaging modalities (e.g., EEG and/or fNIRS).88,89 Taking an approach that simultaneously considers multiple levels of analysis may allow for a more comprehensive understanding of the relative contribution of distinct ...
14 The Gd-DTPA–enhanced MRI can detect new, asymptomatic lesions in patients with active MS,14 as well as lesions correlated with new symptoms.15,16 On repeated scans, new lesions initially demonstrated with Gd-DTPA do not retain their enhanced appearance, suggesting that Gd-DTPA is a marker...
On some occasions, the patients I see may have seizures and I need to assess, test and maintain the safety of the individual when this happens as well as keeping their family calm and reassured. This can be very intense and at times stressful but a key part of my role which I have ...
What specific functional groups does Benedict's test detect? What is bioaugmentation? Give an example. What is an autoantibody? What are ELISA assays used for in labs? What are gliomas and neurogliomas? What is resolving power? What is a bolus? How is it formed? What's an intersection bet...
