If wine leaves a bitter, cotton-like coating on the tongue, neither the sense of taste nor the sense of smell is responsible. The traditional oak barrel character, also called barrique character, is perceived via the trigeminal nerve, which is responsible for, among other things, pain and temperature perception, researchers report. ...
A recent article links some nerve damage after hip surgery to inflammatory neuropathy. Historically, nerve damage from hip surgery has been attributed to mechanical factors caused by anesthesiologists or surgeons, such as positioning of the patient during surgery or direct surgical injury of the nerves. In this study, researchers examined patients who developed inflammatory neuropathies, where the...
Researchers discover the motor cortex plays an active role in learning new motor movements. ...
Researchers discover widespread disruption of signals while the brain is at rest in patients with schizophrenia. ...
A new study reports the protein GDF11 appears to improve brain and skeletal muscle function in older mice. ...
Although there are recommendations for pregnant women to increase their intake of the omega-3 fatty acid docosahexaenoic acid (DHA) to improve fetal brain development, a randomized trial finds that prenatal DHA supplementation did not result in improved cognitive, problem-solving or language abilities for children at four years of age. ...
Scientists have shown that a protein they previously demonstrated can make the failing hearts in aging mice appear more like those of young health mice, similarly improves brain and skeletal muscle function in aging mice. In two separate articles scientists report that injections of a protein known as GDF11, which is found in humans as well as mice, improved the exercise capability of mice equivalent...
Here's another reason to drop that doughnut and hit the treadmill: A new study suggests aerobic fitness affects long-term memory. "The findings show that lower-fit individuals lose more memory across time," said a co-author. The study is one of the first to investigate young, supposedly healthy adults. Previous research on fitness and memory has focused largely on children, whose brains are still developing,...
Autopsies have revealed that some individuals develop the cellular changes indicative of Alzheimer's disease without ever showing clinical symptoms in their lifetime. Additionally, memory researchers have discovered a potential genetic variant in these asymptomatic individuals that may make brains more resilient against Alzheimer's. ...
A protein previously implicated in disease plays such a positive role in learning and memory that it may someday contribute to cures of cognitive impairments, researchers have discovered. The findings regarding the potential virtues of fatty acid binding protein 5 -- usually associated with cancer and psoriasis -- have been outlined in a new article. ...
Researchers report deficiencies in hyaluronan can lead to spontaneous epileptic seizures. ...
Researchers report the protein FABP5, usually associated with diseases such as cancer and psoriasis, enhances cognitive function. ...
Researchers discover a potential genetic variant which could make the brain more resilient to Alzheimer's disease. ...
Researchers have discovered the developmental source of a key type of neuron that allows animals to walk. ...
The developmental source for a key type of neuron that allows animals to walk, a finding that could help pave the way for new therapies for spinal cord injuries or other motor impairments related to disease. The spinal cord contains a network of neurons that are able to operate largely in an autonomous manner, thus allowing animals to carry out simple rhythmic walking movements with minimal attention—giving...
Ischemic brain injury due to heart and vascular surgery causes more than 100,000 deaths annually in Europe and the United States. In addition, approximately 10–20% of patients undergoing heart and vascular surgery – at least 1.5 million people in Europe and the United States every year – suffer from ischemic brain injury as a side-effect of their surgery. Now researchers suggest that they may have...
Controlling blood pressure, cholesterol and irregular heart rhythms are key to stroke survivors avoiding another stroke. Updated guidelines emphasize lifestyle management, including diet, exercise and weight management. Other important updates affect management of narrowed neck arteries and irregular heartbeat. ...
The stress-diathesis theory of suicide suggests a predisposition or diathesis interacts with stressful life experiences and acute psychiatric illness to cause suicidal behavior. The theory explains why only a small minority of individuals are at risk of taking their own lives after exposure to such stressors. The authors of a new article discuss the causes of the diathesis, or predisposition, to suicidal...
Researchers use MRI sensor to map neural activity with molecular precision. ...
Researchers identify two types of neurons which enable the spinal cord to control skilled forelimb movement. ...
