Shared neural network underlying observation and execution of happy facial expressions. The conjunction analysis was FWE-corrected at a threshold of P < 0.05. Shared representations were found in the pars opercularis, the STG extending to the MTG, the precentral gyrus and the (PRE)SMA. This network was less activated in the non-emotional condition (see inserts). Particularly the (PRE)SMA was not activated in the non-emotional facial gesture (see direct comparison in Figure 4). H, happy; NE, non-emotional; N, neutral; OBS, observation; EX, execution.
