Neuroimaging

Researchers have found that individuals who frequently view internet pornography show distinct brain activity and diminished cognitive control. The study suggests that heavy use may impact emotional processing and executive function in ways that resemble patterns seen in substance addiction.

Adults with a history of childhood trauma show measurable differences in brain structure and function, according to new research. The study found smaller surface area and volume in specific cortical regions, along with altered patterns of functional connectivity.

Researchers have discovered that apical and basal dendrites of the same neuron use different strategies to learn, suggesting neurons adapt more flexibly than previously thought. The findings help explain how the brain fine-tunes its wiring during learning.

New research suggests the brain uses a learning rule at inhibitory synapses to block out distractions during memory replay. This process enables the hippocampus to prioritize useful patterns over random noise, helping build more generalizable and reliable memories.

A new study using high-resolution EEG reveals that psilocybin dramatically alters brain connectivity in rats. The psychedelic induced dose-dependent changes in network organization, disrupting normal patterns of neural communication and suggesting rodents may be viable models for studying altered consciousness.

New research using data from over 7,000 children suggests that adversity during late childhood accelerates brain network development. While these changes may buffer against anxiety and depression, they are also associated with poorer school performance.

A new study shows that male and female mice engage distinct brain circuits when responding to threat, challenging the assumption that similar behavior reflects identical brain function. The findings highlight the need for sex-inclusive neuroscience research.

A new study suggests that erythritol, a popular sugar substitute, may harm the cells lining blood vessels in the brain. Lab tests revealed increased oxidative stress, reduced nitric oxide, and impaired clot-busting responses—factors linked to stroke risk.

Researchers examining socioeconomic status and brain health found that family, neighborhood, and regional conditions are differently associated with memory, emotion, and brain connectivity, depending on when in life they occur and what kind of disadvantage is measured.

Researchers have identified increased availability of opioid receptors in the brains of women with anorexia nervosa. The findings suggest that the brain's reward system may function differently in those with the disorder, contributing to restrictive eating patterns.

Scientists are uncovering how tiny grooves in the brain’s surface relate to reasoning ability in youth, showing that deeper sulci may lead to more efficient connections between brain regions critical for complex thought.

New research suggests that the brains of men with lifelong premature ejaculation function differently at rest, with changes linked to emotion, sensation, and neurotransmitter activity—offering new leads for understanding and treating the condition.

Researchers found that fasting improves reproductive success in aging male mice by reducing brain levels of tryptophan and serotonin. The lowered neurotransmitter levels lifted behavioral inhibition and increased sexual activity.

A new study reveals that the brain’s default mode network is made up of distinct anatomical types that support both internal thoughts and external processing. This structural diversity helps explain the network’s role in everything from memory to imagination.

MRI scans show that marathon running can cause a short-term reduction in brain myelin content. The findings suggest that the brain might draw on this fatty substance as a backup energy source during periods of intense physical stress.
