FRENCH MEMORY STUDY. "Explicit memory creation during sleep demonstrates a causal role of place cells in navigation. By triggering intracranial rewarding stimulations by place cell spikes during sleep, we induced an explicit memory trace, leading to a goal-directed behavior toward the place field.” https://lnkd.in/dKCe_Zr View in LinkedIn

“MANIPULATING MEMORIES by tinkering with brain cells is becoming routine in neuroscience labs. Last year, one team of researchers used a technique called optogenetics to label the cells encoding fearful memories in the mouse brain and to switch the memories on and off, and another used it to identify the cells encoding positive and negative emotional memories, so that they could convert positive memories into negative ones, and vice versa.” https://www.theguardian.com/science/neurophilosophy/2015/mar/09/false-memories-implanted-into-the-brains-of-sleeping-mice View in LinkedIn

SYNAPSE SURGERY. "British scientist says memories of spending the night with Marilyn Monroe could be implanted into the brain. Professor Bliss, 75, from the Francis Crick Institute in London, said it was only a matter of time before memory was fully understood and mastered.” http://www.telegraph.co.uk/news/science/12179994/British-scientist-says-memories-of-spending-the-night-with-Marilyn-Monroe-could-be-implanted-into-the-brain.html View in LinkedIn

RESTORING MEMORIES. “If your brain is a library and the books are memories, does Alzheimer’s eat away at the librarian so you no longer have access to those memories, or does it eat away at the books themselves? What it seems to be is it’s actually possible to go in and artificially restore memories that were thought to be gone.” https://lnkd.in/dmPXzVD View in LinkedIn

MEDIA FRENZY. "Creating a False Memory in the Hippocampus. We created a false memory in mice by optogenetically manipulating memory engram–bearing cells in the hippocampus. Our data demonstrate that it is possible to generate an internally represented and behaviorally expressed fear memory via artificial means." (Ramirez et al.). https://lnkd.in/dJBPzNv View in LinkedIn

NOT A CARBON COPY. “Memories can be easily distorted, and a lack of relevant animal models has largely hindered our understanding of false-memory formation. We routinely use memories as guides for cognition and behaviour. Memory, however, can often be unreliable because it is not a carbon copy but rather a reconstruction of the past.” https://lnkd.in/du9NMki View in LinkedIn

RAMIREZ ON TED on his false memory implantation study. "I even see a world where editing memories is something of a reality, because we're living in a time where it's possible to pluck questions from the tree of science fiction and to ground them in experimental reality." https://lnkd.in/d9qh8PB View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the theme of the plant leaf. Few structures have so exemplified life on Earth, nor caused such massive changes as plant leaves, from the vast grasslands to the dense forests. And the more we learn, the more sentient and knowing image of plants have emerged, departing from a stereotype of insensate dumb vegetation. Revisit your smart planetary neighbor with fresh eyes.
