A new study in the journal Current Biology may be the most definitive demonstration yet that the technique can work in nonhuman primates as well as, or even a little better...
No matter what novel objects we come to behold, our brains effortlessly take us from an initial "What's that?" to "Oh, that old thing" after a few casual encounters. In research that helps shed light on the malleability of this recognition process, Brown University neuroscientists have teased apart the potentially different roles that two distinct cell types may play.
