2 days ago · Electroencephalography (EEG) [ 1 ] is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex. [ 2 ]
5 days ago · The relative spectral power of EEG signals in the alpha, beta 3, and gamma waves was significantly affected by the postural head support workstations in digital device users at rest (see Figure 4). The effect of workstations was negligible in the delta, theta, and beta 2 waves.
4 days ago · Subcutaneous EEG provided reliable information on seizure frequency in our selected patient cohort during a 3–6-month monitoring period. Sensitivity of a semiautomatic seizure detection algorithm depended on ictal EEG features. Subcutaneous EEG proved to be a safe and well-tolerated procedure for ultra long-term EEG monitoring in epilepsy ...
Sep 19, 2024 · FoME is pre-trained on a diverse 1.7TB dataset of scalp and intracranial EEG recordings, comprising 745M parameters trained for 1,096k steps. Our model introduces two key innovations: a time-frequency fusion embedding technique and an adaptive time-lateral attention scaling (ATLAS) mechanism.
Sep 24, 2024 · Valence, arousal, and dominance (VAD) are emotion's most famous dimensional representations. Emotions need to be detected both from EEG signals and facial expressions. EEG signals and facial expressions of multiple subjects were analyzed and some emotional features like facial landmarks and power spectral density (PSD) from EEG were extracted.
Sep 6, 2024 · We sought reliable prognostic markers within the color density spectral array (CDSA) of the continuous EEG for AE-affected children undergoing therapeutic hypothermia (TH). Methods: This retrospective study analyzed CDSA data from eight scalp electrodes of 15 AE-affected children undergoing TH.
Sep 10, 2024 · Spectral analysis indicated similar patterns between in-ear and scalp EEG, showing prominent peaks in the alpha range (8-12 Hz) during rest and in the low-frequency range during naps (particularly in the theta range of 4-7 Hz).
