Two opposing ways unsolicited voluntary disclosure of human memory Forget

 (17 October, 2012) - Forget the wrong that was humiliating party last night PAS. It turns out, but we have two opposing ways in which the mind voluntarily to forget unwanted memories that allows, Cell Press journal by October 17, according to a study published in neurons. How to explain the results of experiments dealing with unnecessary control and treatment of memory disorders led growth can improve you can do.


Lead study author Roland MRC BENOIT said: "This research due to two distinct mechanisms before such a demonstration is another alternative memory from system memory to capture awareness with recall system to facilitate by providing other benefits, "Cognition and Brain Sciences Unit in Cambridge University's.

Previous studies have found that people with awareness can prevent voluntary memories. Although many neuroimaging studies of the brain mechanisms involved in a deliberately examined, the cognitive strategies that people use, or have not accurately reflect the strength of nerve. Two possible ways to forget unwanted memories or suppress their memories with more alternatives are needed, and this strategy can engage distinct neural routes.

To test this possibility, MRC Cognition and Brain Sciences Unit BENOIT and Michael Anderson Magnetic resonance imaging uses active volunteers who between pairs of words and then tried to block them from either learned association out the brain activity or forget the memories alternative inspection recalling memories.

Although strategies were equally effective, they activate distinct neural circuits. During memory suppression, brain structure called the dorsolateral prefrontal cortex activity in hippocampus inhibited, the major area for the last events mentions. Awareness of specific memories in the presence brought memories of worry involved in two areas - on the other hand, memory replacement tail midventrolateral prefrontal cortex and prefrontal cortex was supported by.

"Better understanding of these mechanisms and disorders such as posttraumatic stress disorder characterized by memory loss that regulation down understand how they can help," said BENOIT. He knows everything that will help contribute to a different process, because they perform well in one or the other approach may be naturally can. '
