#AllaKatsnelson in @thetransmitter, on #SheenaJosselyn's work on #engrams.

I like #TheTransmitter for their accessible writing on #neuroscience. It's building bridges for interested people, without over-simplification.

»They seemed to be catching a glimpse of a real-time competitive mechanism in which the #neurons with the ramped up #CREB expression were primed to jump into an #engram. They had found what they were looking for.«

Spent some quality time with my Glove80 and Engram-based layout yesterday. I think this is, in fact, the end game. I’m still at 0 wpm on MonkeyType (having not used it or practiced for a couple of weeks), but it just feels really nice.

Neuroscientists successfully test theory that forgetting is actually a form of learning https://medicalxpress.com/news/2023-08-neuroscientists-successfully-theory.html

Adaptive expression of engrams by retroactive interference https://www.cell.com/cell-reports/fulltext/S2211-1247(23)01010-0

Highlights
• Retroactive interference causes forgetting by the competition of two memory engrams
• Forgotten engrams can be expressed or updated by reexposure to training cues
• Artificial reactivation of engram cells rescues interference-induced forgetting
• Interference is an active process that requires the activation of the suppressed engram

these findings indicate that retroactive interference modules engram expression in a manner that is both reversible and updatable. Inference may constitute a form of adaptive forgetting where, in everyday life, new perceptual and environmental inputs modulate the natural forgetting process.
