Older adults with more severe hearing loss are more likely to suffer from dementia, but the likelihood of developing dementia was lower for those who use hearing aids.
Older mice were less capable than younger mice at "turning off" certain actively firing neurons when exposed to ambient noise. The result causes a fuzzy soundscape that makes it difficult for the brain to focus on one type of sound and filter out other surrounding sounds.
Irisin, a hormone secreted into the blood during high endurance and aerobic exercise, reduces levels of alpha-synuclein and restores movement in mouse models of Parkinson's disease.
Both those who experienced a natural near-death experience and those who had a near-death experience while taking psychedelics report less fear of death and a lasting, spiritual positive experience.
Glycan, a special sugar protein, appears to play a significant role in the development of Alzheimer's disease.
Researchers have identified a mechanism that occurs within the CA3 region of the hippocampus that appears to be responsible for a common type of age-related memory loss.
A new study reveals blind people remember speech and language better than sighted people. Researchers say blind people use language as a mental tool to remember information.
The repetitive nature of days we faced during the COVID-19 lockdowns may have made our memories and time perception murky. Researchers report on how COVID-19 has impacted our memory, causing a pandemic memory fog.
Providing free or low-cost vision care and eyeglasses to children helped improve academic performance and behavior, researchers report.
Findings upend the long-standing belief that blind people lack deep knowledge of visual phenomena.
Using human stem cells to develop a brain organoid model, researchers were able to show exposure to a common pesticide synergizes with an autism-linked gene mutation. The study provides clear evidence that genetics and environment may combine to disrupt neurodevelopment.
Combining machine learning with neuroimaging data, researchers identified a brain region that appears to govern contextual associations.
