Meditation-induced neuroplastic changes of the prefrontal network are associated with reduced valence perception in older people.

ABSTRACT:

Background

Neuroplastic underpinnings of meditation-induced changes in affective processing are largely unclear.

Methods

We included healthy older participants in an active-controlled experiment. They were involved a meditation training or a control relaxation training of eight weeks. Associations between behavioral and neural morphometric changes induced by the training were examined.

Results

The meditation group demonstrated a change in valence perception indexed by more neutral valence ratings of positive and negative affective images. These behavioral changes were associated with synchronous structural enlargements in a prefrontal network involving the ventromedial prefrontal cortex and the inferior frontal sulcus. In addition, these neuroplastic effects were modu
