A new generation of brain scanner, that can be worn like a helmet allowing patients to move naturally whilst being scanned, has been developed. It is part of a five-year Wellcome funded project which has the potential to revolutionize the world of human brain imaging.
In the largest study of its kind, genetic changes causing neurodevelopmental disorders have been discovered. The study of almost 8,000 families found for the first time that mutations outside of genes can cause rare developmental disorders of the central nervous system. The study is a positive step towards providing an explanation for children with undiagnosed neurodevelopmental disorders.
A team of neuroscientists are inching closer to developing the tools needed to decipher the brain. Now, the team has demonstrated how these proteins can be used as tools to regulate the activity of individual neurons in the brain through changes in temperature. These tools will advance fundamental brain research and potentially lead to 'deep brain stimulation' treatments used for Alzheimer's and Parkinson's patients.
Deep neural networks (DNNs), which have been developed with reference to the network structures and the operational algorithms of the brain, have achieved notable success in a broad range of fields, including computer vision, in which they have produced results comparable to, and in some cases superior to, human experts. In recent years, DNNs have also been expected to be useful as a tool for studies of the brain.
Excess body weight has been linked to poor academic performance in children in several previous studies. A new study now shows that a high body fat percentage is associated with poor reading skills in 6- to 8-year-old boys. However, these associations are largely explained by poor motor skills.
Freezing the nerve that carries hunger signals to the brain may help patients with mild-to-moderate obesity lose weight, according to a newly presented study. The treatment was determined safe and feasible in the initial pilot phase.
The origin of the Dravidian language family, consisting of about 80 varieties spoken by 220 million people across South Asia, can be dated to about 4,500 years ago, based on new linguistic analyses. An international team used data collected first-hand from native speakers and analyzed these using cutting-edge computational methods. The findings shed light on the prehistory of these languages and their speakers.
The cerebral cortex consists of a large diversity of neurons, each displaying specific characteristics in terms of molecular, morphological and functional features. But where are these neurons born? How do they develop their distinct properties? Scientists have discovered a unique molecular factor allowing them to track, from birth to maturity, a homogeneous class of neurons called the neurogliaform cells.
It is a principle of modern architecture that less may be more. This principle does not apply to information as a basis of far-reaching decisions, it seems. But: Many people shy away from going to the doctor’s, because they are afraid of unpleasant truths, such as the diagnosis of a disease. Researchers have developed a method to overcome this fear.
Alzheimer's disease is most often characterized by two different pathologies in the brain: plaque deposits of a protein called beta-amyloid and tangles of another protein called tau. A new article offers new insight: tau production and secretion from nerve cells appears to be an active process in the natural course of Alzheimer's disease, which may explain why experimental treatments targeting tau have had disappointing results.
