Magnetic source imaging MSI makes it possible to identify the cortical area in the human brain whose activity reflects the decay of sensory storage of information about sounds echoic memory. The lifetime for decay of the neuronal activation trace in primary auditory cortex is found to range from 0.8 sec to 3.4 sec for the subjects studied. Extensive behavioral studies that determine the duration of memory for the loudness of a tone show that these physiological measures predict the lifetime of echoic memory to within the uncertainty of 0.2 sec for each of the subjects.
