Chinese scientists explained why we should never go to bed angry – in a similar state, the brain fixes negative emotions and we will hardly forget this bad memory, Daily Mail said. According to the Beijing University team, the nightmare helps to reorganize negative memories in the brain, making them harder to erase.
Scientists say the results of their research may shed further light on post-traumatic stress and its consequences.
Our ability to erase negative memories constitutes an essential part of mental health.
In this process, blood flow to the hippocampus is activated, where new memories are formed.
But after sleep, the activity moves to the neocortex, the outer brain area associated with the highest functions.
That is the manner by which negative feelings are combined.
Scientists have attempted to remove bad memories with 73 students whose brain was subjected to scanning.
