The amygdala, an important brain center of emotion processing, is located deep within the human brain. Amygdala activation can be measured by magnetic resonance imaging (MRI) and used for neurofeedback. Of course, the use of this method is limited because MRIs are expensive and available only at a few clinics. With the electrical fingerprint (EFP), an innovative method of measuring the activation of deep brain structures is available, which does not require the MRI. On the basis of the brain waves, which are derived via the scalp with electroencephalography (EEG), characteristic activation patterns are reconstructed (Meir-Hasson et al., 2016). Neurofeedback of the amygdala is hereby more readily available and cheaper (Keynan et al., 2019, 2016) than with MRI. In this project, we examine the relationship between amygdala activation and EFP. We test whether patients from the adolescent center benefit from EFP neurofeedback training.

By training, people can learn to self- control activation of different brain regions. This ability to control one's own brain activity can be learned by the so-called "neurofeedback" (for a review, see Sitaram et al., 2017). In neurofeedback, as the name implies, subject receives feedback about the current level of activation of a particular brain region (eg amygdala, insula, prefrontal cortex, ...).
However, can people also learn to perceive different brain states? This question is the object of this study. In order to answer this question, participants first receive EEG-based neurofeedback, which indicates amygdala activity (see the project Brain training using "electrical fingerprint"). Thus, the participants learn to control the activation of their own amygdala, which plays an essential role in the processing of emotions. In addition, the participants also go through sections of the experiment in which they no longer receive feedback and are supposed to estimate themselves how high their own activation is. It is then tested whether the participants are able to make more accurate estimates in the course of 10 training appointments.
