WebNormal EEG during drowsiness in an 8-year-old child, illustrating background theta and delta frequency slowing and a “drowsy burst” of frontally dominant theta activity in the third and fourth seconds. 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.

WebRelatedly, parietal delta and frontal theta oscillations are also known to be involved with the generation and modulation of the P3 (Başar-Eroglu et al., 1992; Bachman and Bernat, 2024), and therefore, increases in P3 and in low frequency EEG activity may reflect changes in similar neural substrates.
