- Аннотация: The role of cingulate cortex in time perception is still being discussed. Some studies demonstrate primary role of anterior cingulate cortex (ACC) in time perception (Mies, 2011; van der Veen, 2011), whereas the others revealed posterior cingulate cortex (PCC) involvement in this process (Hirono, 1998). We analyzed the relation between the sizes of different cingulate cortex regions and subjective time perception. Subjects: 25 right-handed females (mean age – 61 years old). We performed magnetic resonance morphometric analysis of T1 images in order to measure absolute square surfaces (in mm^2) of three cingulate cortex regions – anterior (BA 24), posterior (BA 23), and retrosplenial (BA 26, 29, 30; RCC) areas of both hemispheres. To assess subjective time perception we asked the subjects to estimate assessment duration and one minute interval. We calculated non-parametric correlations (p < 0.05) between individual behavioral and morphometrical data. We revealed positive correlations between subjective estimation of assessment duration and the sizes of ACC (r=0.61), PCC (r=0.52) and RCC (r=0.43) in the left hemisphere; subjective minute estimation correlates negatively with the size of right RCC (r=-0.45). According to the results, subjective time perception is related to the left cingulate cortex functioning. The revealed correlations are higher for the ACC than for the PCC and also PCC size correlates with time perception better than RCC size. Thus, we revealed retrosplenial-rostral gradient of cingulate cortex involvement in subjective time perception.
