WebOct 27, 2010 · Consecutive EEG recordings showed a background pattern of 8–9 Hz which slowed towards 7–8 Hz. These recordings increasingly showed repetitive runs of bilateral synchronous theta activity of 4–6 Hz frontotemporally, which lasted 1–3 s. Photic flash stimulation provoked a photomyogenic response (Fig. 1). Stimulation with repetitive ... WebMar 23, 2024 · The photoelectric response of organic field-effect transistors (OFETs) will cause severe photoelectric interference, which hinders the applications of OFETs in the light environment. It is highly challenging to relieve this problem because of the high photosensitivity of most organic semiconductors. Here, we propose an efficient "exciton ...

WebJun 13, 2024 · 1 point: 12 hours of EEG screening may exclude seizure with ~95% sensitivity. ≧2 points: 24 hours of EEG screening or more may be needed if the goal is detection of >95% of all seizures. (1) This is all based on an initial EEG recording of one hour (which may be longer than the duration of a spot EEG at many centers). WebJan 15, 2024 · The ZnTe microsphere photodetector shows an obvious photoelectric signal and good stability. The rise and decay times of the photodetector are 96.93 ms and 103.57 ms, respectively, and the response time is much faster than that of the recently reported photodetectors based on ZnTe nanomaterials.
WebFurthermore, it is proposed that both the EEG changes and the associated clinical symptomatology (as well as changes in level of anesthesia, which vary with arterial PCO2) may be explained by altered arousal, and that the vasoconstriction observed during hyperventilation is a central neurogenic response to hypocapnia at a brainstem level. http://upandrunningnetworks.com/files/C188_2.pdf
