'Amnesiac' mice made to remember what they forgot with blue light
Mice with amnesia were able to recover training memories with assistance from blue light, in research that suggests that memories lost in brain trauma could still exist (and perhaps even be recalled) from the human brain. It marks the first time scientists were able to suppress a memory and then bring it back. The research focused on retrograde amnesia, which affects the ability to form memories after a brain injury, or recall what happened before the accident. The group trained two mice teams to remember that one room would deliver a mild electric shock when entered into. Afterwards, placing the mice in the room would cause this reaction without even delivering the shock. Researchers then identified which neurons were active in mice brains when they froze at being in the shock room. labelling those cells with a protein sensitive to blue light, and using a virus to get it where they wanted it. When blue light hit these "memory engram cells" the mouses experienced the same shock — and froze up.
Breakfast Topic: Doncha hate it when...
...you're doing a collection quest and you don't understand why the widgets aren't dropping -- until you realize you're grinding in the wrong area?And doncha hate it when you're just a few pulls away from finishing an instance when your main tank says, "Sorry guys, I've got to go, I didn't realize it was so late"?And doncha hate it when you finally grab that last pig's spleen, turn around to head back to the quest hub -- and walk right into an elite who sends you back for a corpse run?And doncha hate it when you go to turn in a quest after leaving an instance run... and then realize you left the quest item back on the last boss' corpse?I mean doncha? What else do you hate in game?
