Brain Activity in PTSD: Trauma Memories Differ from Sad Ones

A new study reveals distinct differences in brain activity between traumatic memories in PTSD patients and regular sad autobiographical memories. This research, the first of its kind to examine real-life personal memories, found that traumatic memories do not activate typical memory-related brain regions like the hippocampus, suggesting they're not processed as regular memories.

Brainless Brittle Stars Learn by Association

Researchers discovered that brittle stars, brainless marine creatures, can learn through experience, a finding that challenges our understanding of learning and intelligence. The study revealed that brittle stars, relatives of starfish, could learn to associate darkness with feeding times through classical conditioning, similar to Pavlov's dogs.

Enhanced TMS Shows Promise as Depression Treatment

Researchers have modified transcranial magnetic stimulation (TMS), significantly improving its effectiveness in treating hard-to-treat depression. In a recent study, this novel TMS protocol achieved a 66% response rate and 42% acute remission in patients with major depressive disorder, surpassing the standard FDA-approved protocol's 29% response rate.

Reshaping the OCD Brain: How Therapy Alters Neural Connectivity

A new study reveals that exposure and response prevention (EX/RP), a primary therapy for obsessive-compulsive disorder (OCD), effectively reshapes brain connectivity. This therapy enhances cognitive control by strengthening connections within key neural networks. Using advanced MRI techniques, researchers observed significant changes in the frontoparietal, cingulo-opercular, and default mode networks among OCD patients who underwent EX/RP compared to those who received stress management training.

Persistent Brain Repair Signals in Ex-NFL Players

A new study on former NFL athletes reveals prolonged high levels of the repair protein TSPO, indicating long-term brain inflammation post-injury. This protein, usually elevated after a traumatic brain injury (TBI) as part of the immune response, was found at high levels years after athletes ended their sports careers.
