A blood factor involved in weight loss and aging

October 22, 2019 0 Comments Brain Tumor, Dementia, Diet and Weight Loss, Dieting and Weight Control, Hypertension, Intelligence, Nutrition Research, Obesity

Aging can be delayed through lifestyle changes (physical exercise, restricting calorie intake, etc.). Researchers have elucidated the properties of a molecule in the blood – GDF11 – whose mechanisms were previously unknown. In a mouse model, they showed that this molecule could mimic the benefits of certain calorie restrictions – dietary regimens that have proven their efficacy in reducing cardiovascular disease, preventing cancer and increasing neurogenesis in the brain.

How the brain dials up the volume to hear someone in a crowd

October 21, 2019 0 Comments Brain Injury, Brain-Computer Interfaces, Disorders and Syndromes, Intelligence, Language Acquisition, Learning Disorders, neuroscience, Perception

Our brains have a remarkable ability to pick out one voice from among many. Now, a team has uncovered the steps that take place in the brain to make this feat possible. Today's discovery helps to solve a long-standing scientific question as to how the brain's listening center can decode and amplify one voice over others. It also stands to spur development of hearing-aid technologies and brain-computer interfaces that more closely resemble the brain.

Novel nanoprobes show promise for optical monitoring of neural activity

October 19, 2019 0 Comments Biochemistry, Brain-Computer Interfaces, Electronics, Intelligence, Nanotechnology, neuroscience, Optics, Psychology

Researchers have developed ultrasensitive nanoscale optical probes to monitor the bioelectric activity of neurons and other excitable cells. This novel readout technology could enable scientists to study how neural circuits function at an unprecedented scale by monitoring large numbers of individual neurons simultaneously. It could also lead to high-bandwidth brain-machine interfaces with dramatically enhanced precision and functionality.

Fundamental insight into how memory changes with age

October 17, 2019 0 Comments Alzheimer's Research, Brain Injury, Children's Health, Dementia, Elder Care, Healthy Aging, Intelligence, Memory

New research could help explain why memory in old age is much less flexible than in young adulthood. Through experiments in mice the researchers discovered that there were dramatic differences in how memories were stored in old age, compared to young adulthood.
