Salience Network of the Human Brain focuses on the multiple sources of stimuli that compete for our attention, providing interesting discussions on how the relative salience-importance or prominence-of each of these inputs determines which ones we choose to focus on for more in-depth processing.
The salience network is a collection of regions of the brain that select which stimuli are deserving of our attention. The network has key nodes in the insular cortex and is critical for detecting behaviorally relevant stimuli and for coordinating the brain's neural resources in response to these stimuli. The insular cortex is a complex and multipurpose structure that plays a role in numerous cognitive functions related to perception, emotion, and interpersonal experience-and the failure of this network to function properly can lead to numerous neuropsychiatric disorders, including autism spectrum disorder, psychosis, and dementia.
Lucina Uddin is head of the Brain Connectivity and Cognition Laboratory at the University of Miami, Florida. Her research focuses on the relationship between brain connectivity and cognition in typical and atypical development. Her research utilizes advanced neuroimaging approaches including analysis of dynamic network interactions to understand the neural basis of neurodevelopmental disorders such as autism. She is the recipient of numerous honors and awards, including a 2014 NARSAD Young Investigator grant and a career development award from NIMH. She is the author of more than 60 journal articles.
