Estrogen Levels at the Moment of Trauma Predict PTSD

High estrogen levels at the moment of trauma increase the brain's "plasticity," making it more vulnerable to PTSD. This biological state helps explain why women face higher PTSD risks.

Brain Signal Linked to OCD Compulsions Identified

A newly identified high-frequency brain signal in the frontal cortex appears to drive compulsive behaviors in OCD. In three severe cases, briefly disrupting this activity through targeted deep brain stimulation rapidly reduced symptoms, offering hope for more precise and responsive treatments.

Neural Afterburn: Brain Rewires Itself to Boost Endurance

Building endurance isn't just about muscles, it's about the brain. New research suggests that a specific "afterburn" of brain activity following a workout is the secret to getting stronger, effectively rewiring your neural circuits to power your heart and lungs.

Hunger, Fear, and the Brain’s Hidden Switch to Turn Off Chronic Pain

Chronic pain affects nearly 50 million Americans, yet new research reveals the brain may have an internal switch that can turn it down. Scientists identified a group of neurons in the brainstem that regulate long-term pain by integrating signals related to hunger, fear, and thirst.

Psilocybin Rewire Brain Circuits Tied to Pain and Mood

New research shows that psilocybin, the active compound in psychedelic mushrooms, can reduce both chronic pain and pain-related depression by modulating brain circuits rather than acting at the site of injury. In mouse studies, a single dose provided pain relief and mood benefits lasting nearly two weeks by targeting the anterior cingulate cortex.

Music May Help Kids Understand Emotions, Even Without Empathy

Music plays a powerful role in how we perceive and express emotion—and a new study finds that even very young children can match emotions in music to facial expressions. Researchers studied 144 children aged 3 to 5 and found that emotion recognition improves with age.

Brain’s Social Hub Responds to Confusion, Not Just People

New research reveals that the brain region often linked to understanding others, the dorsal medial prefrontal cortex (DMPFC), is activated more by uncertainty than by social reasoning alone. Using fMRI, researchers found DMPFC responded to uncertain inferences about people, bodies, and even objects.

Brain ‘Reset Wave’ May Explain How ECT Rapidly Relieves Depression

Electroconvulsive therapy (ECT), long misunderstood due to outdated portrayals, remains the most effective treatment for severe, treatment-resistant mental illness. While traditionally thought to work solely through induced seizures, new research reveals that ECT also triggers a second brain event: cortical spreading depolarization (CSD).

Brain-Targeted mRNA Delivery Breaks the Blood-Brain Barrier

Researchers have developed lipid nanoparticles (LNPs) that cross the blood-brain barrier (BBB) and precisely target brain cells, a major step toward treating neurological diseases like Alzheimer’s. By attaching short peptides to LNPs, scientists achieved targeted mRNA delivery to neurons and endothelial cells, avoiding invasive procedures. Peptides are smaller, more stable, and easier to use than antibodies, making them ideal for LNP-based therapies.

Brain’s Quit-or-Wait Dilemma: How We Decide to Persist or Move On

New research sheds light on how the brain's prefrontal cortex evaluates whether to persist or quit in uncertain situations. Using tasks mimicking real-life dilemmas, researchers found that different brain regions influence patience and adaptability.

Lab-Grown Tumor Models Mirror Glioblastoma Treatment Response

Glioblastoma organoids, lab-grown replicas of a patient’s tumor, accurately predict how the tumor responds to CAR T cell therapy. This breakthrough allows real-time testing of therapies, showing that responses in the organoid closely mirror those in the patient.

Ketogenic Diet Enhances CAR-T Cancer Therapy

Researchers have found that a ketogenic diet boosts CAR T cell therapy effectiveness by enhancing tumor control and survival in mice with lymphoma. The key is beta-hydroxybutyrate (BHB), a metabolite produced during ketosis, which CAR T cells prefer as an energy source over glucose. Laboratory models showed that BHB supplementation led to complete cancer remission in most mice and enhanced CAR T cell expansion.
