Neuroimaging

A new study suggests that not all sitting is created equal. While frequent TV watching is linked to reduced brain volume, mentally engaging desk work is linked to preserved brain structure in older adults.

Brain imaging reveals that LSD works by quieting local electrical rhythms and severing small-scale synchronization in the cortex. This fragmentation forces the brain to globally integrate sensory data, fundamentally altering human consciousness and perception.

A new study reveals exactly what happens in the brain when we read for pleasure instead of information. By tracking blood flow, researchers found that the brain temporarily mutes word-processing regions before engaging areas linked to imagination and empathy.

By analyzing the brain scans of intoxicated humans and rats, scientists have validated a new mathematical tool that successfully tracks the brain’s inhibitory system. This non-invasive measure could help researchers better understand various mental health conditions.

A recent study published in NeuroImage reveals that while human brains naturally synchronize during cooperative video games, this mental alignment does not guarantee success. High neural synchrony was actually linked to worse strategic performance.

As global temperatures rise, a new study provides evidence that heat exposure during early development may slow the growth of a central brain region, potentially linking early environmental stress to later childhood behavioral changes.

New research shows that the microscopic structure of specific brain pathways is linked to how people experience trauma-related flashbacks. Variations in white matter integrity may determine whether traumatic memories manifest as spontaneous intrusions or vivid sensory reliving.

The human brain utilizes deep folds to maximize the storage capacity of neural tissue. New anatomical research shows the physical symmetry of one specific fold linked to emotional processing behaves differently in boys with autism spectrum disorder.

A new study explores the complex link between high-fat diets and Alzheimer's risk. Researchers found dietary fat is associated with faster brain atrophy in healthy older adults, but a slower rate of decline in those with mild cognitive impairment.

Researchers have mapped a neural pathway that instantly induces fear. Activating this circuit caused prolonged anxiety in mice, while temporarily turning it off completely blocked the effects of severe stress.

A new study explores why it's so hard to stop watching short videos. Researchers found that watching your favorite clips temporarily shuts down the brain's self-control centers, and this effect may be linked to your brain's natural chemistry.

A new computer simulation based on brain scans shows how LSD alters the balance of excitement and inhibition in specific neural circuits. These chemical changes silence sensory pathways and boost abstract thought, unifying the brain into a highly synchronized state.

A new review of brain scans reveals that people with psychiatric disorders, especially schizophrenia, tend to have a physically smaller pineal gland. However, this anatomical difference doesn't appear to directly influence how well they sleep at night.

A new study suggests that hunger amplifies our immediate enjoyment of sweetness, regardless of calories. The research also reveals that regular consumers of artificial sweeteners show heightened brain activity in areas linked to self-control.

A new study reveals how antidepressant medications physically change the brain. Researchers found that treating chronic depression normalizes abnormal brain tissue microstructure, suggesting the initial abnormalities were actually the brain’s attempt to cope with severe symptoms.
