A study in Brain Communications reveals that individuals with aphantasia, who cannot voluntarily create mental images, show no increase in brain activity during motor simulations, contrasting sharply with those who can visualize movements, indicating profound neural differences.
Researchers at the Paris Brain Institute have mapped the "wave of death" in rat brains, a phenomenon marking the cessation of brain activity post-anoxia.
A new study suggests that a single PET scan measuring amyloid beta levels in the brain can effectively predict the rate of cognitive decline in older adults, potentially streamlining early Alzheimer's diagnosis and management.
A recent study found that preadolescent boys with anxiety disorders exhibit significant white matter changes in the brain, unlike girls, suggesting sex-specific neural alterations.
Combining psilocybin with meditation enhances brain connectivity and information flow, according to new research. This was evidenced by increased centrality in brain networks, suggesting improved cognitive integration.
In a study recently published in the Journal of Affective Disorders, researchers have found evidence suggesting that certain types of gut bacteria may influence the thickness of the brain's cortex.
Researchers discovered that deep sleep quality, specifically in the brain's right temporoparietal junction, correlates with higher prosocial behaviors like cooperation and charity.
Researchers have found that a single dose of creatine can temporarily enhance cognitive functions impaired by sleep deprivation. This study suggests creatine as a potential non-stimulant alternative for boosting brain performance when sleep is compromised.
Infants from four months old can anticipate and react to objects moving towards them, showing early signs of understanding spatial interactions and developing self-awareness through sensory integration.
Recent research identified distinctive brain activity patterns and genetic markers that differentiate postpartum depression and postpartum depression with anxiety. These findings could lead to more precise diagnostics and treatments.
Researchers discovered that the cerebellum is essential for learning new tasks through rewards. When a specific area of the cerebellum was deactivated in monkeys, their ability to learn new visual and motor associations was significantly impaired.
Individuals with severe depressive symptoms and those experiencing stressful life events show significant alterations in the nucleus accumbens volume and other brain regions, highlighting a bidirectional relationship.
A recent study reveals how drugs like cocaine and morphine hijack brain pathways, disrupting natural reward processing and potentially offering new targets for addiction treatments.
A new study highlights that adolescent exposure to Xanax may lead to enhanced sensitivity to opiates like morphine in adulthood, suggesting long-term neurobiological changes from early drug use. This raises concerns about prescribing such medications during critical developmental stages.
A recent study revealed that drugs blocking opioid and dopamine receptors diminished brain activity related to rewards in the medial orbitofrontal cortex and other areas. However, these changes did not translate into any observable behavioral differences among participants.
