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

FALSE MEMORIES. “Neuroscientists in France have implanted false memories into the brains of sleeping mice. Using electrodes to directly stimulate and record the activity of nerve cells, they created artificial associative memories that persisted while the animals snoozed and then influenced their behaviour when they awoke.” https://www.theguardian.com/science/neurophilosophy/2015/mar/09/false-memories-implanted-into-the-brains-of-sleeping-mice View in LinkedIn

PRIMARY SOURCE OF ENERGY. "A true measure of their success in terrestrial environments is the capacity of leaves to endure climatic extremes between the tropics and the tundra whilst simultaneously facilitating the global scale net fixation of approx. 207 billion tonnes of CO2, 56.4 x 10(15) g C year(-1). This primary production provides energy for virtually all forms of terrestrial life on Earth, especially tetrapods and insects, and links many ecosystem and biogeochemical processes." http://aob.oxfordjournals.org/content/96/3/345.full.pdf View in LinkedIn

GIANT IMPACT. "Megaphylls altered the evolutionary trajectory of terrestrial plant and animal life, the biogeo-chemical cycling of nutrients, water and carbon dioxide and the exchange of energy between the land surface and the atmosphere." http://aob.oxfordjournals.org/content/96/3/345.full.pdf View in LinkedIn

FLAT BIG LEAVES. "The vast majority of the estimated 250 000 or so extant species of flowering plants, as well as most gymnosperms and (extinct) pteridosperms, utilize(d) a flat-bladed megaphyll with a network of veins to capture solar energy for photosynthetic carbon assimilation." http://aob.oxfordjournals.org/content/96/3/345.full.pdf View in LinkedIn

TWO LINEAGES. "Plants evolved leaves on at least two independent occasions and the legacy of these historic evolutionary events is represented in extant floras by microphylls in lycophytes (clubmosses, spikemosses and quillworts) and megaphylls in euphyllophytes (ferns, gymnosperms and angiosperms)." http://aob.oxfordjournals.org/content/96/3/345.full.pdf 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.

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
