Altered neural functioning, like that experienced in patients with Parkinson's disease, changes the way art is both perceived and valued. People with neurological motor dysfunction demonstrated decreased experiences of motion in abstract art and enhanced preferences for high-motion art, compared to a healthy control group.
New research indicates that the common fruit fly can travel tens of kilometers in a single flight when in search of food.
International team of researchers identifies cognitive computations underlying human predictive behaviour.
Genome wide analyses have revealed that MSEI, a gene linked with anemia is also associated with insomnia. The correlation between the two conditions, however, remains largely unexplored in adults. Thus, in a cross-sectional study, researchers assessed the relation between anemia and insomnia in a large Chinese cohort. Their findings, published in Chinese Medical Journal, suggest that anemia increases the risk of insomnia. Further studies can help elucidate the underlying molecular and physiological associations.
Rising levels of dementia is putting pressure on residential aged care facilities, including in rural and regional centres where nursing homes and staff are already under pressure. Now a pilot program of personalised interventions, including residents' favourite songs, has been shown to make a big difference to dementia behaviours, drug use and carers' wellbeing.
Research by investigators at Harvard Medical School illuminates the neurobiology that underlies food attraction and how hungry mice choose to pay attention to one object in their environment over another.
Neuroscience researchers at Mayo Clinic Orthopedics and Sports Medicine in Rochester, Minnesota, U.S., the Health and Technology District and Simon Fraser University (SFU) in Surrey, British Columbia, Canada have published the latest results of their ongoing multi-year hockey concussion study examining changes in subconcussive cognitive brain function in male youth ice hockey players. The research showed that repetitive subconcussive impacts triggered compounding effects in brain function changes.
Spinal cord nerve cells branching through the body resemble trees with limbs fanning out in every direction. But this image can also be used to tell the story of how these neurons, their jobs becoming more specialized over time, arose through developmental and evolutionary history. Salk researchers have traced the development of spinal cord neurons using genetic signatures and revealed how different subtypes of the cells may have evolved and ultimately function to regulate body movements.
New biomarkers for Alzheimer's disease are a priority area for researchers seeking to learn more about the disease and find possible methods of early diagnosis. Researchers at Karolinska Institutet in Sweden have now studied a new PET tracer that is an important diagnostic tool for the disease. The study on the tracer substance BU99008, which is published in Molecular Psychiatry, can play a key part in the early identification of signs of Alzheimer's disease.
Mice with symptoms that mimic Bardet-Biedl Syndrome (BBS) have difficulty with learning and generating new neurons in the hippocampus. However, according to a new study by Thomas Pak, Calvin Carter, and Val Sheffield of the University of Iowa, published April 22nd, 2021 in the journal PLOS Genetics, these mental defects can be successfully treated with lithium.
