Difference due to memory

<p>Difference due to memory (Dm) indexes differences in neural activity during the study phase of an experiment for items that subsequently are remembered compared to items that are later forgotten. It is mainly discussed as an <a href="/facts/Event-related_potential/B9N1eaMG">event-related potential</a> (ERP) effect that appears in studies employing a subsequent <a href="/facts/Memory/zucwQIEX">memory</a> paradigm, in which ERPs are recorded when a participant is studying a list of materials and trials are sorted as a function of whether they go on to be remembered or not in the test phase.  For meaningful study material, such as words or line drawings, items that are subsequently remembered typically elicit a more positive waveform during the study phase (see Main Paradigms for further information on subsequent memory). This difference typically occurs in the range of 400–800 <a href="/facts/Millisecond/xHCyv235">milliseconds</a> (ms) and is generally greatest over centro-parietal recording sites, although these characteristics are modulated by many factors.
