Two groups of healthy adults (young: 25.2 years; old: 65.2 years) were submitted to an fMRI scanning while performing the Reading the Mind in the Eyes test, which requires the attribution of a mental state to the other person focussing only on the eye-gaze. There was no difference in the behavioural performances between young and old and both groups of subjects activated the pSTS and the TP, thus indicating that old people show no impairment of mentalizing circuits. However, a relevant shifting of the neural circuit implied in each group to solve the task emerged. Old subjects showed a more bilateral activation of frontal areas and a stronger involvement of the linguistic components of the mirror neuron system (i.e. area 44), as compared to young. Both young and old participants activated the non-linguistic components of the mirror neuron system, such as area 6. These findings are discussed taking into account the recent literature dealing with cognitive functions during normal aging.
