Abstract: Mind wandering (MW) understood as those thoughts that occur spontaneously which are "task unrelated" and/or "stimulus independent", represents a state of decoupled attention where, instead of processing information from the external environment, attention is directed towards personal private thoughts or feelings and, whereas all individuals spend significant amount of their waking time mind wandering (15-50%), is often thought to have adverse consequences such as to deteriorate mood. Moreover, several studies have shown a positive correlation between mind wandering and depression, where individuals diagnosed with Major Depressive Disorder (MDD) are less in the "here and now" and prone to rumination. The most common treatment to treat depression is based on pharmacological antidepressants and Cognitive therapy, although recent therapies like Mindfulness-Based Cognitive Therapy (MBCT) have shown positive results helping patients disengage from automatic thoughts and thus reduced the severity of their depression. Another well accepted technique to increase awareness of brain activity is Neurofeedback (NFB), which, by providing real time feedback of the individuals electroencephalogram (EEG), can help them regulate their neural activity and may be used as an aid to meditation. However, few studies have looked at neural correlates of MW in MDD diagnosed patients to develop a potential NFB system based on neural markers to make those patients aware that their mind is wandering, with the objective of assisting them in changing their attentional control. For that reason our research proposal (MWALERT) is based on identifying the neural correlates of Mind Wandering using EEG, to, once identified, design a NFB system based on providing an alarm to patients when their mind starts to wander, with the ultimate goal to develop a smartphone-based application connected with a portable EEG, so that patients can benefit from such technology in a non-clinical environment making it more accessible.
