Abstract

Current research focuses on neural similarities between people with close social ties. The restricted social proximity of two people would be significantly associated with the similarities of neuronal responses related to the allocation of attention, the narrative interpretation and the affective response, during the presentation of an exogenous stimulus. These responses are influenced by personal knowledge, opinions, interests and values, and the causality of these similarities is not yet defined. In addition, similarities were also found at rest in the functional connectivity of the brain between two people close to a network. This resemblance persists controlling for personality factors and demographic variables. Thus the similarities between friends would not be just a simple impression, but a very real concordance at the level of the brain
