Reproduced with permission and modified from (Raz, 2004; Raz & Buhle, 2006). Attentional networks as identified by fMRI (and in line with (Petersen & Posner, 2012). This figure is meant to illustrate that different attentional processes can be subserved by different attentional networks. The authors propose the existence of three attentional networks, the alerting, the orienting and the executive (see also note 5 for further description of brain networks). The alerting network shows thalamic activation, the orienting network shows parietal activation, and the executive network anterior cingulate cortex activations.
