  • It’s almost a good thing that we’ve never been entirely able to figure out how human memory works, because if we did, we’d probably just forget.

      Shows just how unreliable our brains truly are
  • Working memories, it seems, are preserved in a latent or hidden state, existing without any evident activation at all until the moment they’re needed.

      Reminds me of learning about a new topic for a class and then somehow remembering the concept during an assessment.
  • ...5 more annotations...
  • Instead, however, while there was indeed detectable neural activity for the so-called attended memory item (AMI)—the one that the subjects knew they would need right away—there was none at all for the unattended memory items (UMI), which the subjects might also need, but not until later.
  • All the same, when subjects were asked about a UMI, a peak appeared for it just as it did for an AMI. In both cases, working memory worked just fine, but in one case it did so without the benefit of any visible storage system.
  • unattended memories are maintained in what the researchers called “a privileged state” only as long as they had to be.
  • Whatever the explanation, the work has implications for understanding not just memory but other cognitive functions like perception, attention and goal maintenance.
  • if noninvasive brain stimulation techniques can be used to reactivate and potentially strengthen latent memories”—in other words, recovering information that had been forever lost.
