Kelekis, Efstathios P. Efstathopoulos In the present case study, we investigated possible emotional connectedness between monozygotic twins by means of functional magnetic resonance imaging (fMRI). During the experimental condition, Twin 2 was randomly selected to participate in the neuroimaging protocol while Twin 1 participated in the experimental condition outside the MRI scanner (none of them was aware of the experimental procedure). The experimental condition included two sessions with visual and acoustic stimuli, respectively. Between the two experimental conditions, there was a 2-min break with Twin 1 (i.e., the subject outside the scanner) relaxing with eyes closed. Data analysis revealed significant brain activation in three regions, namely left orbitofrontal gyrus (during visual condition) and left cingulum and precentral gyrus (during the acoustic condition). Our findings denote emotional connectedness between a pair of monozygotic twins using fMRI. Further studies in larger sample sizes are needed to investigate if this is a generalized and systematic phenomenon or an incidental finding.
