How quickly do we experience the benefits of exercise? A new study of healthy older adults shows that just one session of exercise increased activation in the brain circuits associated with memory – including the hippocampus – which shrinks with age and is the brain region attacked first in Alzheimer’s disease.
Using a unique computational framework they developed, a team of scientist cyber-sleuths has identified 104 high-risk genes for schizophrenia.
Reduced connectivity between the amygdala and ventrolateral prefrontal cortex has been identified in children on the autism spectrum who exhibit disruptive behaviors, compared to those on the spectrum who do not. Findings suggest this distinct brain network could be independent of core autism symptoms.
A specially designed computer program can help diagnose post-traumatic stress disorder (PTSD) in veterans by analyzing their voices.
Using CRISPR-Cas9 gene editing, researchers identified actionable pathways responsible for the growth of glioblastoma stem cells. By reverse engineering brain cancer cells, multiple potential new targets for cancer treatments have been uncovered.
Obesity is associated with alterations in brain structure, including lower grey matter volume and smaller globus pallidus volume according to new research.
Researchers have found certain clues in the brain waves that show the reason why angry dreams occur when a person sleeps. The results of the study titled, “EEG Frontal Alpha Asymmetry and Dream Affect: Alpha Oscillations Over the Right Frontal Cortex During REM Sleep and Pre-Sleep Wakefulness Predict Anger in REM Sleep Dreams,” were published in the Journal of Neuroscience.
People with the specific genotype of the Cannabinoid receptor 1 gene may be more prone to cannabis use disorder.
A rapid memory system transition from the hippocampus to the posterior parietal cortex is stabilized as we sleep. Sleep and repeated rehearsal of memory jointly contribute to long-term memory consolidation.
A new study confirms that a simple blood test can reveal whether there is accelerating nerve cell damage in the brain.
Finally, this week, using a combination of movie clips and neuroimaging, researchers find people have positive biases to those they feel are more like them, even if they are unable to see the person’s face.
