Caffeine may worsen brain grey matter loss during sleep deprivation, potentially hindering recovery and exacerbating the negative effects of chronic sleep restriction, new research reveals.
Adolescent alcohol use is linked to larger hippocampal volumes, while tobacco and cannabis show no such effect, revealing substance-specific impacts on brain development.
Both sighted and blind individuals show similar brain adaptations, including increased activity in visual and auditory cortices, after 10 weeks of echolocation training, demonstrating the brain's adaptability.
Stanford researchers identified six depression subtypes using brain imaging and machine learning, enabling personalized treatment predictions and improving outcomes based on specific brain activity patterns.
A neuroimaging study found that pornographic stimuli elicit stronger brain reward responses than monetary and gaming stimuli in healthy men, highlighting pornography's potent impact on neural reward circuits.
Habitual entrepreneurs display higher cognitive flexibility and increased gray matter in the left insula, according to new research.
Damage to the magnocellular mediodorsal thalamus in monkeys causes behaviors similar to human paranoia, suggesting this brain region's critical role in paranoia development and potential treatment targets.
Familiar chocolates prompt quicker brain reactions, but unfamiliar chocolates trigger stronger brain responses, especially in regions linked to decision-making and reward processing.
Music composers exhibit more efficient neural pathways and stronger functional connectivity in key brain regions, particularly the orbitofrontal cortex, compared to non-musicians.
Neuroimaging research has found that psilocybin increases self-inhibition in visual brain regions and enhances top-down connectivity, leading to vivid, internally generated visual imagery with eyes closed.
A study found that creative individuals exhibit reduced brain responses to surprising stimuli, suggesting they process the importance of information differently, which may help explain their unique thinking patterns and ability to notice unconventional details.
Early adversity leads to smaller hippocampal volume in children, but faster right hippocampal growth, which is associated with an increased risk of depression later in childhood.
Researchers identified heightened activity in the ventral striatum and reduced communication with the anterior insula in bipolar disorder, linking these brain areas to extreme mood shifts and reward perception.
Role-playing disrupts brain-to-brain synchrony, with effects varying by cultural background and sex, suggesting different cognitive processing during social interactions across these factors.
Scientists have found that changes in the brain's default mode network can predict dementia with over 80% accuracy up to nine years before diagnosis, outperforming traditional methods.
