Neural Noise Shows the Uncertainty of Our Memories

In the moment between reading a phone number and punching it into your phone, you may find that the digits have mysteriously gone astray--even if you've seared the first ones into your memory, the last ones may still blur unaccountably. Was the 6 before the 8 or after it? Maintaining such scraps of information long enough to act on them draws on an ability called visual working memory. For years, scientists have debated whether working memory has space for only a few items at a time or if it just has limited room for detail: Perhaps our mind's capacity is spread across either a few crystal-clear recollections or a multitude of more dubious fragments.
