New research in the Proceedings of the National Academy of Sciences reveals both conscious rehearsal and unconscious reactivation enhance memory. But unconscious cues, unlike conscious ones, enrich memory context without harming related memories.
A study found that 24-month-olds remember screen-based information better than 15-month-olds, especially if they nap within 4 hours of learning. Longer naps further improved recall. This highlights sleep's role in enhancing memory consolidation in infants, offering insights for integrating screen...
A meta-analysis revealed that creatine supplements enhance memory, particularly in older adults aged 66-76. Benefits are consistent across different genders, intervention durations, and geographical origins.
A study in Memory & Cognition finds reading aloud boosts memory recall but not deeper comprehension of material. Despite vocalization's clear benefit for remembering details, it doesn't enhance understanding beyond memorization, challenging the effectiveness of this strategy for comprehensive learning.
Researchers found that our brains react differently to smiles on faces we think are deepfakes, rating them less positively than real smiles. However, our reactions to anger remain consistent, showing that while fake smiles fail to fully engage us, we're...
In a pioneering study published in Nature Human Behavior, researchers from Virginia Tech and collaborators have made significant strides in understanding the neurochemical basis of social interactions, focusing on the roles of dopamine and serotonin.
Scientists have discovered that the somatosensory cortex, responsible for touch, also influences our perception of time. Using optogenetics on rats, they found that touch and time perception are interconnected, opening new research avenues in neuroscience.
A study found bias-reduction training improved decision-making in real-world scenarios by 29%. Despite skepticism, the training, which included a computer game, showed promise in reducing confirmation bias among graduate business students.
New research reveals we can swiftly gauge a crowd's trustworthiness by averaging faces' features, even with brief glances. This ability to form "ensemble perceptions" helps us make quick social decisions.
Harvard researchers discovered that zebrafish can develop complex neural circuits and behaviors without sensory input, suggesting genetics alone may shape brain connectivity.
Through a novel verbal associative task, researchers demonstrated how sleep strengthens weak connections and forms new associations between event elements, enhancing our ability to recall interconnected details from minimal cues. This process, linked to sleep spindles, underscores sleep's vital function...
Australian scientists' study in Human Brain Mapping shows brain function during tasks is partly genetic. This insight into how genes and environment shape our cognition and emotion processing could lead to personalized mental health interventions.
Recent research has illuminated why foods high in fats and sugars seem so irresistible. Through detailed study, scientists discovered separate brain pathways activated by fats and sugars, which significantly heighten our desire for such foods. This insight into the gut-brain...
Scientists discovered a gene, "RetroMyelin," from ancient viruses, essential for myelination in vertebrates, suggesting viral sequences in early vertebrate genomes were pivotal for developing complex brains. This breakthrough in Cell unravels how myelination evolved, highlighting its significance in vertebrate diversity.
Researchers discovered dopamine plays a crucial role in adapting decisions to changing situations. Using PET and fMRI scans, they found dopamine increases in the brain's reward center during task changes, aiding learning from mistakes.
