事件相关电位（ERPs）记录在识别任务的线条画（项目）或图纸及其空间位置（源）。识别图纸引起更多的积极ERP比新的图纸。独立的空间判断的准确性，在源识别任务的旧/新的效果是更大的前额叶头皮，和更长的时间比在项目识别任务，这表明源记忆任务从事一个定性不同的记忆过程。更多的后头皮网站敏感的准确性的来源判断，但这种效果是延迟相对于研究和未研究的图纸之间的差异，这表明，源记忆过程完成后，项目识别。空间源记忆和其他刺激属性的连接记忆之间的异同进行了讨论，以及前额叶皮层在记忆中的作用。
Event-related potentials (ERPs) were recorded during recognition tasks for line drawings (items) or for both drawings and their spatial locations (sources). Recognized drawings elicited more positive ERPs than new drawings. Independent of accuracy in the spatial judgment, the old/new effect in the source recognition task was larger over the prefrontal scalp, and of longer temporal duration than in the item recognition task, suggesting that the source memory task engaged a qualitatively distinct memory process. More posterior scalp sites were sensitive to the accuracy of the source judgment, but this effect was delayed relative to the difference between studied and unstudied drawings, suggesting that source memory processes are completed after item recognition. Similarities and differences between spatial source memory and memory for conjunctions of other stimulus attributes are discussed, together with the role of prefrontal cortex in memory.
