Hofmann, in Reference Module in Neuroscience and Biobehavioral Psychology, 2021 Self Dimensions Brain Networks Associated With the Self I will then highlight its crucial role in switching between systems involved in processing exogenous and self-relevant information and briefly discuss key features of SN development from infancy to adulthood, concluding with an examination of how characterization of SN dysfunction is leading to a more thorough understanding of psychopathology.ĭanielle M. I describe the core functions of this network in attention and cognitive control, focusing on the AI as a dynamic hub for detection and selection of salient stimuli and for mediating interactions with other neurocognitive systems. I then focus on identification of the SN, highlighting its key nodes and their functional and structural connectivity patterns.

I begin with a brief outline of saliency and general saliency detection mechanisms in the brain. This article summarizes recent progress in our understanding of the SN its functional and structural organization its role in cognition, emotion, and development and its disruption in psychopathology. Decoding subject-driven cognitive states with whole-brain connectivity patterns. R., Ryali, S., Rykhlevskaia, E., Menon, V., & Greicius, M. The Journal of Neuroscience, 27, 2349–2356 Shirer, W. Dissociable intrinsic connectivity networks for salience processing and executive control. The salience network has distinct patterns of intrinsic cortical and subcortical connectivity from the lateral frontoparietal central executive network in the anterior thalamus (antTHAL), dorsal caudate nucleus (dCN), dorsomedial thalamus (dmTHAL), hypothalamus (HT), periaqueductal gray (PAG), putamen (Put), sublenticular extended amygdala (SLEA), substantia nigra/ventral tegmental area (SN/VTA), and temporal pole (TP). (B) Cortical and subcortical nodes of the salience network (shown in red).

(A) (a) The salience network (SN) is readily identified as an intrinsically connected large-scale network that is distinct from (b) the dorsal attention network anchored in the frontal eye field and intraparietal sulcus and (c, d) the left and right lateral frontoparietal central executive networks. Salience network identification using independent component analysis.
