A new study finds sound waves from the voice effectively transmit information beyond the lexical meaning of words.

A new study offers clues about how to prevent inflammation of brain tissue, which promotes Alzheimer’s disease (AD). The findings of this study online now and appearing in the September 4, 2019 print issue of the journal Neuron, could contribute to the development of new therapies for AD.

Partial sight has been restored to six blind people via an implant that transmits video images directly to the brain.

People with a family history of Alzheimer’s disease perform worse on learning tasks than those without a genetic link to the disease. The learning impairments appear to be exacerbated by the APOE E4 gene and diabetes.

Restless REM sleep disrupts the adjustment of memory traces during sleep. This may increase negative emotions associated with mental health disorders.

Functional regions within the brain become less distinct and inter-connected in the elderly over time, especially in those networks related to attention span and cognition. The finding, published by researchers at Duke-NUS Medical School in the Journal of Neuroscience, adds to the current understanding of longitudinal decline in brain network integrity associated with aging.

Researchers at EPFL’s Blue Brain Project, a Swiss Brain Research Initiative, have developed a new framework to work out how a single neuron in the brain operates.

Finally this week, with the help of data collected from an online app, researchers have developed a machine learning algorithm which is 90% accurate in determining subsets of behavior associated with autism.
