Our research group focuses on the neurobiological mechanisms of social attachment. We explore cognitive and sensory changes in social isolation and loneliness and investigate how social connection influences the processing of traumatic experiences. We test possible changes in social perception not only with visual and auditory items, but also with tactile and olfactory stimuli. In addition to classical behavioral and hormonal measurements, we use non-invasive brain stimulation (transcranial direct current stimulation), psycho-physiological measurements (e.g. EDA, ECG and respiration in social dyads) and imaging techniques (fMRI 1.5 to 7 T and fNIRS).
