The future is scary.
We live in a world where, you can hold a device in your hand that allows you to access an unlimited amount of information, in any language, and share this information with people on the other side of the planet in a matter of seconds. Just when you think our society couldn’t get any more futuristic, scientists always have to one up themselves and amaze everyone.
In a discovery straight out of Eternal Sunshine of the Spotless Mind, researchers at the University of California in San Diego were able to erase, and then reactivate memories in the brains of genetically engineered rats.
The researchers were able to stimulate neurons in the brains of rats with a series of pulses that have been shown to strength or weaken connections in between brain cells. This is the first study to be able to directly show the strengthening or weakening of these connections, known as synapses.
Scientists said that the results of the study proved they could casually manipulate the brain of a rat. The lead author, Sadegh Nabavi said in a news release that “We can cause an animal to have fear and then not have fear and then to have fear again by stimulating the nerves at frequencies that strengthen or weaken the synapses”
