PREDICTING MEMORY FAILURE. “Researchers developed an algorithm that predicted with high accuracy whether a person would remember a given word. By stimulating the brain only when a person read words that were likely to be forgotten, the researchers could boost performance by up to 140%. Penn psychologist Michael Kahana says that the team has recorded from the brains of about 80 people in total and is seeking regulatory approval to use a more precise electrode array.” https://lnkd.in/d6RG5sQ View in LinkedIn

“PROFESSOR TIM BLISS (winner of the Brain Prize) predicts that we will soon be able to manipulate memories, suggesting that we understand memory sufficiently today.” https://lnkd.in/dnaUMmN View in LinkedIn

DECODING MEMORY. “I think that memory is one of the essential faculties of mind which we will eventually understand almost completely. I wouldn’t say that about other faculties of mind such as consciousness. For memory, I think we've got a pretty good handle on what happens.” https://lnkd.in/dm6ThY5 View in LinkedIn

MALLEABLE MEMORIES. “Once the realm of science fiction, advances in technology, neurochemistry, and cognitive science are redefining what memory is, enabling us to erase old memories and implant new ones.” https://lnkd.in/dsfzvCm View in LinkedIn

MEMORY ABLATION. “Memory erasure has been shown to be possible in some experimental conditions; some of the techniques currently being investigated are: drug-induced amnesia, selective memory suppression, destruction of neurons, interruption of memory, reconsolidation, and the disruption of specific molecular mechanisms." https://en.m.wikipedia.org/wiki/Memory_erasure View in LinkedIn

FEAR MEMORIES. “Memories of fear could be permanently erased, study shows.” https://lnkd.in/d8E-U_W View in LinkedIn

LASERS FOR MEMORY. “Ramirez co-authored a 2014 study in which he and a team from RIKEN-MIT Center for Neural Circuit Genetics were able to change bad memories to good in male mice. Using a technique called optogenetics, in which genetically encoded, light-responsive proteins are inserted into cells, the scientists were able to pinpoint where a mouse's negative memory of a shock to the foot was formed, in the neural circuitry that connects the dentate gyrus in the hippocampus to the amygdala. The researchers then manipulated those neurons with lasers. Each time the mice ventured to a certain part of their enclosure, the negative memory was reactivated, and they quickly learned to fear the area.” https://lnkd.in/dkBjap4 View in LinkedIn

“XENON gas, an anesthetic already used for humans, to modify memory reconsolidation in mice. The gas inhibits NMDA receptor activity. Dosed within an hour after a foot shock, it significantly reduced fear reactions, both to the shock and to its context, compared with controls.” https://lnkd.in/dkBjap4 View in LinkedIn
