Web• EEG is used to record brain electrical signals from sensors placed on the scalp, in some cases, using a water-soluble gel. • TMS is a procedure in which magnetic fields outside of the head are used to stimulate electrical activity in certain parts of the brain, causing it to be either more or less active. WebAside from the usual background findings and artifacts, EEGs will often have normal variant patterns that, to an untrained eye, may appear to be epileptiform or otherwise pathological and thus are at risk of being overcalled and leading to unnecessary tests or treatments.
