MIT researchers have shown, for the first time ever, that memories are stored in specific brain cells 다운로드. By triggering a small cluster of neurons, the researchers were able to force the subject to recall a specific memory. By removing these neurons, the subject would lose that memory 다운로드.
As you can imagine, the trick here is activating individual neurons, which are incredibly small and not really the kind of thing you can attach electrodes to 이미지 파일 다운로드. To do this, the researchers used optogenetics, a bleeding edge sphere of science that involves the genetic manipulation of cells so that they’re sensitive to light 다운로드. These modified cells are then triggered using lasers; you drill a hole through the subject’s skull and point the laser at a small cluster of neurons 다운로드.
…we should note that MIT’s subjects in this case are mice…
The main significance here is that we finally have proof that memories are physical rather than conceptual 다운로드.
