WebAn event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. More formally, it is any stereotyped … WebIntroduction. The electroencephalogram ( EEG) is a recording of the electrical activity of the brain from the scalp. The first recordings were made by Hans Berger in 1929 although similar studies had been carried out in animals as early as 1870. The waveforms recorded are thought to reflect the activity of the surface of the brain, the cortex. WebERPs can be reliably measured using electroencephalography (EEG), a procedure that measures electrical activity of the brain over time using electrodes placed on the scalp. The EEG reflects thousands of simultaneously ongoing brain processes. crazy mardi gras beads

"Web7 apr. 2024 · Before the advent of modern neuroimaging, EEG was the best noninvasive tool to use in searching for focal lesions. In the last few decades, with progress in imaging techniques, the role of EEG is changing; its use for localization of a brain lesion is being superseded by neuroimaging. The use of EEG outside of epilepsy has declined markedly. " - Minimal brain activity on eeg meaning
