They Identify the Pattern of Brain Activity Associated With Nightmares


It is quite common in humans to have nightmares, a state of sleep that can cause fear and even anger, and now researchers are trying to know what part of our brain emits those bad dreams that you do not want to have at any time.

An investigation that will be published in the journal JNeurosci, has been able to track the part of the brain that is responsible for generating feelings of anger in people who sleep.

And with this study, researchers believe they have identified a pattern of brain activity that predicts the anger experienced during dreams. If true, this study could explain the neural bases of the emotional content of nightmares, which are often associated with mental and sleep disorders such as anxiety, depression and insomnia.


In this test, carried out by the researcher Pilleriin Sikka, and also by its partners from the University of Finland, University of Sweden and the University of Cambridge (UK), an emotional mechanism shared between the two has been discovered states of consciousness



For this, the researchers obtained electroencephalography recordings of 17 healthy individuals during two separate nights in a sleep laboratory. After the patients achieved REM (Rapid Eye Movement) sleep, they were awakened by the researchers and asked to describe their dreams and rate the emotions they experienced.

Many participants reported feeling angry and having more neuronal activity in the right half of their frontal cortex, suggesting that part of the brain is responsible for poor sleep.

The study has its limitations, mainly because it has been carried out under laboratory conditions, but the researchers point out that their findings provide support for theories according to which dreaming is a realistic simulation of waking life.
