Scientists Map the Neural “Entrapment” Patterns that Keep the Depressed Brain Stuck
Researchers at Icahn School of Medicine used high‑resolution MRI and diffusion tractography combined with network control theory to map the brain's energy landscape in major depressive disorder. They identified four recurring whole‑brain states and found that patients with depression repeatedly bounce between a sensory‑focused State 3 and a default‑mode State 2, creating a loop that requires higher energetic effort. The study shows that the depressed brain is trapped in a deep basin of the energy landscape, making transitions to healthier states costly. These dynamics may explain the subjective feeling of being "stuck" and point to new targets for neuromodulation and drug therapies.
