APOEe4, a gene associated with Alzheimer's disease risk, doesn't appear to directly affect memory performance or brain activity in older adults without cognitive impairment. However, the gene does seem to influence brain regions and systems that older at-risk adults activate to support successful memory recall.
A child's mental health is affected by stress factors experienced during the mother's pregnancy. The findings suggest the COVID-19 pandemic will have a lasting detrimental impact on the mental health of many children born to mothers who are currently pregnant.
Is it possible to have a psychedelic experience from taking a placebo alone? A new study says it is.
Using Cappella recordings, researchers discover humans have developed complementary neural systems in each hemisphere for auditory stimuli.
Combining fMRI and behavioral data, researchers examined gender identity in cisgender and transgender individuals using a new machine learning algorithm. The AI identified at least nine dimensions of brain-gender variation.
Combining artificial intelligence technology and blood samples, researchers were able to predict and explain the progression of Alzheimer's and Huntington's disease. The new algorithm was able to detect alterations in gene expression over decades from patients' blood samples.
Canada's Nunavik Inuit population are genetically distinct from any other known population. Certain genetic variants identified in this population are associated with a higher risk of brain aneurysms. Nunavik Inuit have distinct genetic signatures in pathways linked to lipid metabolism, allowing them to adjust to higher-fat diets and the extreme temperature of the Canadian Arctic.
