Some of the memories with amnesia erased from memory. Some scientists believe that this is associated with impaired ability to recall information and memories do not disappear. The second theory was closer to the truth, Zee News writes, citing the results of research experts from the Massachusetts Institute of technology.
With the help of unconditioned stimuli and drug anisomycin-causing in animals retrograde amnesia, scientists have modeled the experiment with laboratory mice. The impact of blue light on the light-sensitive cells return unconditional memories of animals in the experimental group.
It's hard to say how the experience gained will be applicable to humans, however due to the small discoveries, doctors will be able to understand how to reclaim memory in patients with amnesia.
