非侵入性脑磁图使人们有可能识别大脑皮层区域，其活动反映了听觉刺激信息的被动感觉存储（回声记忆）的衰减。初级听觉皮层神经元激活轨迹的衰减寿命被发现可以预测由精神病理学确定的对音调响度的记忆持续时间。虽然对特定音调的响度的记忆丢失了，但记忆中的响度会朝着受试者在一系列试验中所接触到的所有响度的全局平均值衰减。
Noninvasive magnetoencephalography makes it possible to identify the cortical area in the human brain whose activity reflects the decay of passive sensory storage of information about auditory stimuli (echoic memory). The lifetime for decay of the neuronal activation trace in primary auditory cortex was found to predict the psychophysically determined duration of memory for the loudness of a tone. Although memory for the loudness of a specific tone is lost, the remembered loudness decays toward the global mean of all of the loudnesses to which a subject is exposed in a series of trials.
