Timing of Prozac Treatment Shapes Lasting Mood, Brain Changes

New research reveals that the developmental timing of fluoxetine (Prozac) treatment profoundly influences long-term mood and brain function. In a rodent model, early postnatal treatment in males led to persistent anxiety and depression-like behaviors, while adolescent treatment reduced these behaviors.

Emotional Neglect in Childhood Undermines Trust in One’s Own Body

A new meta-analysis links childhood emotional abuse and neglect to reduced trust in one’s bodily signals, highlighting the long-term mental health risks. Researchers analyzed 17 studies with 3,705 participants, finding that while maltreatment did not generally impair interoception, emotional maltreatment was strongly tied to lower body trust.

Astrocytes in Obesity: Brain Cells That Control Metabolism & Cognition

A new study reveals that astrocytes, star-shaped brain cells in the striatum, are key players in how obesity alters brain function and metabolism. Researchers showed that manipulating astrocyte activity in obese mice improved their cognitive flexibility and metabolic regulation.

Stem Cell Grafts Show Promise in Repairing Myelin in MS

A new study reveals that neural stem cell grafts can generate new myelin in the central nervous system, offering hope for treating progressive multiple sclerosis (MS). Researchers showed that induced neural stem cells matured into myelin-producing oligodendrocytes and safely integrated into damaged regions in a mouse model.

Early Meals Boost Health, but Genetic Clock Shapes When We Eat

Our bodies process food differently depending on the time of day, and eating later has been linked to poorer metabolic health. A study of twins found that those who consumed most of their daily calories earlier had better insulin sensitivity and lower risk factors for diabetes and obesity.

Retinal Cells Rewire to Preserve Vision in Degenerative Eye Disease

New research shows that retinal neurons can rewire to preserve vision in retinitis pigmentosa, a genetic disease causing blindness. Using mouse models, scientists found that rod bipolar cells adapt by forming functional connections with cone cells when their usual rod partners degenerate.

Positive Emotions Boost Memory

A new study shows that positive emotions can enhance memory, even for meaningless information. Researchers recorded brain activity as participants viewed neutral squiggles paired with positive, neutral, or negative emotional images.

Anxious Mondays Leave Lasting Mark on Stress

A new study reveals that anxiety felt on Mondays uniquely elevates stress hormones, even in retirees, with potential consequences for heart health. Researchers found older adults who reported Monday anxiety had 23% higher long-term cortisol levels than peers anxious on other days.

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.

Why Your Brain Is Better at Gossip Than You Realize

A new study reveals how humans instinctively calculate who to gossip with by weighing popularity and social distance. This cognitive process allows gossip to spread widely while minimizing the risk of it reaching the wrong person.

Blurry Beginnings Shape Brain’s Visual Pathways

New research reveals how early-life blurry, low-color vision may help shape the brain’s visual pathways into specialized systems. Using computational models trained on low-quality images followed by high-quality ones, scientists showed this developmental trajectory produces distinct magnocellular and parvocellular-like processing.

Human Brains Keep Making Memory Neurons in Adulthood

A groundbreaking study shows that the human hippocampus continues producing new neurons well into late adulthood. Researchers identified neural progenitor cells—the precursors to neurons—in adults up to 78 years old, confirming ongoing neurogenesis in the memory center of the brain.
