Scientists have long suspected that the brain stores memories of an event in many different places, not at a single point. A recent study has given solid evidence about that.

Research, done on mice, but is believed to be true for humans as well.

" This is the first time we have found 'fragments' on the brain of an event once thought to be a unique memory ," said James McGaugh, a neurobiologist at Irvine University, California. know.

" For example, different facts of the event, like a car accident, will be handled in different brain regions ," McGaugh said. " Memory is scattered in our brains, although we think it is a unique event ."

In the experiment, each mouse was shocked, while one tablet was inserted into three different areas of the brain. Two days later, their memories of this frightening memory were checked, and the pills revealed parts of the brain that worked.

The finding here is: the hippocampus (hippocampus) treats memories of the context, while the prefrontal cortex stores information about the uncomfortable stimulus, while the nucleus reinforces common memory. common and the effect of remembering both unpleasant information and context.

" The more we understand the specificity of memory, the more we know why and how the processing of memory can be distorted - the cause of pathological problems involving many forms. bias in perception, "said Thomas Carew, Dean of the Department of Neuroscience and Behavior of the University.
