Discovery of the day
A study using task and resting-state fMRI identifies hyperconnectivity within a large-scale brain subnetwork involving the default mode and dorsal attention networks as a neural mechanism linking childhood neglect to major depressive disorder. Researchers found that functional connectivity strength and task-rest similarity within this network independently mediated the relationship between neglect and depressive symptom severity in patient and control groups. For your work developing preclinical models of placebo analgesia in chronic pain, these findings provide a critical mechanistic framework for understanding how early-life adversity may shape pain-related brain network dysfunction and treatment response.
