The human brain is characterized by highly dynamic patterns of functional connectivity. However, it is unknown whether this time-variant ‘connectome’ is related to individual differences in the personality traits described in the five-factor model. To answer this question, inter-network time-variant (non-stationarity) connectivity was computed in n=818 healthy people via a dynamical conditional correlation model. Next, network dynamicity was quantified throughout an ad-hoc measures (T-index) and the generalizability of the multi-variate associations between personality traits and network dynamicity was assessed using a train/test split approach. Conscientiousness, reflecting enhanced cognitive and emotional control, was the sole personality trait linked to stationary connectivity across several circuits such as the default mode and prefronto-parietal networks. The stationarity in the ‘communication’ across large-scale networks offers a mechanistic explanation of the capacity of conscientious people to ‘protect’ non-immediate goals against interference over-time. This study informs future research aiming at developing more realistic models of the brain dynamics mediating personality differences.
