Blocking microglia activity in young mice prevents infantile amnesia and enhances memory, indicating these brain immune cells play a key role in early memory formation and forgetting. doi.org/hbkphs
Blocking immune cells in the brain can prevent infantile amnesia
Scientists have found that blocking microglia (specialist immune cells in the brain) prevents infant forgetting ("infantile amnesia") and improves memory in mice, suggesting that microglia may actively manage memory formation and dictate what, and when, we forget.

Last week, Sarah Power (@sarahdpower.bsky.social) dazzled us with her unique research. Her research program is one of a kind: she combines precise mouse neuroscience with bold toddler behavioral methods to study infantile amnesia. Hire her!

talking about AI as a bubble doesn't make sense. AI/tech has become integrated into critical social/financial infrastructure means fall of AI = fall of these institutions. just like govnt's bailed banks during the financial crisis, they will do same with AI so long as AI remains social infrastrctr
