A new study in twins suggests that daily protein and prebiotic supplements (inulin and FOS) can improve memory test scores in people over 60, potentially impacting early detection of Alzheimer's and offering new approaches to healthy aging.
This module uses NextBrain, a probabilistic atlas of the human brain, to segment ~300 distinct ROIs per hemisphere on in vivo or ex vivo scans. Segmentation relies on a Bayesian algorithm and is robust against changes in MRI pulse sequence.
Neuroscience research suggests that scientists may have been undervaluing the most ancient regions of the human brain when studying consciousness. Evidence indicates that the subcortex and cerebellum may play a more significant role than previously thought, and could even be sufficient for basic forms of consciousness.
Scientists have mapped the activity that takes place across a mouse's entire brain as it decides how to complete a task - and the results could explain the origin of our gut feelings.
An international research team found that cats prefer to sleep on their left side, potentially as an evolutionary advantage for hunting and escape behavior. Sleeping on the left allows them to process threats with the right hemisphere of the brain, which specializes in spatial awareness and rapid movements.
A new study reveals how the brain determines whether a smell is pleasant or revolting, highlighting the role of the amygdala and two genetically distinct cell types that can assign either positive or negative value to odors. This discovery could lead to treatments for anxiety, PTSD, or sensory disorders.
Researchers have found that the total surface area (TSA) of the cerebral cortex is linked to cognitive performance, while mean cortical thickness (MCT) is associated with schizophrenia risk. The study used Mendelian randomization to establish causal relationships between cortical morphology and neuropsychiatric traits.
A new study reveals that caffeine increases the complexity of brain activity during sleep, especially in younger adults, potentially disrupting the brain’s ability to recover overnight. Researchers used EEG and AI to analyze sleep in 40 adults after caffeine or placebo intake, identifying less predictable brain signals and increased wake-like brainwave patterns.
A new scientific review maps the cellular and molecular mechanisms behind memory formation, consolidation, generalization, and updating, revealing how memories are stored, altered, and even manipulated in the brain. Key breakthroughs allow scientists to visualize and activate specific neurons involved in memory, offering deeper insight into how learning occurs and how fear memories may become overgeneralized in disorders like PTSD.
This article explores the connection between strategic thinking in games like chess, the behaviors of manipulators (like drug dealers), and the neurological basis of 'theory of mind' – our ability to understand others' perspectives. A recent study suggests a link between forward-thinking and manipulation, with brain activity during negotiation mirroring that seen in chess players.
