BROOKLYN , N.Y. — Whether it ’s messy breakup or a traumatic elevator car crash , there are some memories many of us would rather erase from our minds . Although the idea was explore in the 2004 film " Eternal Sunshine of the Spotless Mind , " the entire erasure of witting memories is no longer completely science fabrication , says a neuroscientist who has been experimenting with such possibilities in rats .
New York University neuroscientist Joseph LeDoux ’s preliminary studies suggest the musical theme of erasingmemorieslike a painful romantic breakup ( as was the case in " Eternal Sunshine " ) is potential in man .
Jim Carrey plays a man who has his memory erased in “Eternal Sunshine of the Spotless Mind."
" What [ the moving-picture show grapheme ] were doing , obviously , is unimaginable , " LeDoux told an audience at a showing of the film here at the Brooklyn Academy of Music , as part of a program called Science on Screen . But " it ’s not so far - fetched as you might reckon , " LeDoux say . [ 5 Things You Must Never Forget ]
In " Eternal Sunshine , " the characters Joel ( Jim Carrey ) and Clementine ( Kate Winslet ) are a brace who have broken up , and Clementine decides to undergo a medical procedure to have her retention of Joel erased . When Joel finds out , he decides to undergo the same procedure , but it does n’t completely work , and he finds himself running around in his thinker , essay to safeguard his storage of Clementine .
The memories depicted in the film — such as Joel ’s memory of meeting Clementine on Montauk beach on Long Island , N.Y. — are a form of conscious storage . A mentality region calledthe hippocampus , tucked aside in the secular lobe , consolidates forgetful - term memories to long - term conscious memories .
In contrast , LeDoux ’s work seeks to erase unconscious forms of store . The corpus amygdaloideum , another brain region deep in the secular lobe , action memory to make responses to a particular stimulus , such as learning to dread a threat .
In edict to tinker with storage , you first have to empathize that memory are n’t right-down record you may just look up , LeDoux said . Each time you retrieve something , you reconstruct it , so your store of an case is only as good as your last recollection of it . When memory are reconstructed , nerve cell in the encephalon green groceries protein , which assert the connection between the electric cell .
In 2000 , LeDoux ’s post - doctoral scholarly person Karim Nader did an experimentation in which he took a rat with a memory of a fearful experience and throw in the animal with a drug that obstruct protein deduction . later , the rat ’s unconsciousfearful memory was wipe out . The informer might still have had the conscious memory of the frightening experience , but it no longer had an emotional reaction to it .
In a signified , what " Eternal Sunshine " showed was the opposition . The fictitious character lose their witting retention of each other , but retain an aroused connection . Of naturally , the filmmakers occupy some artistic license , describe Joel as a small manikin inside his own head that was separate from the relaxation of his mind .
The twenty-four hours when scientist can erase these form of conscious memories may be a long room off . But besides LeDoux , other investigator have already experimented withimplanting memoriesin mice , or creatingmemory prosthetic gadget .
Above all , the picture instance just how important retentiveness is to human identity . As LeDoux put it , " We are our memory , essentially . "
