USA: A cross-sectional study comprising 2,822 US adults revealed that worse examination-based and self-reported vision impairment is associated with anxiety and depressive symptoms, and worse examination-based vision impairment is linked with severe social isolation.

These findings, published in JAMA Ophthalmology, provide evidence to support prioritizing research aimed at enhancing the health and inclusion of people with vision impairment.

Vision impairment and psychosocial function, including symptoms of anxiety, depression and social isolation, are a major cause of morbidity in the US. However, there is a lack of nationally representative studies evaluating associations between subjective and objective vision impairment with psychosocial function following the COVID-19 pandemic.

Musk said that the first human patient implanted with a Neuralink chip last month “is able to… move the mouse around the screen just by thinking.”

Elon Musk announced this week that his company’s brain implant has allowed a person to move a computer mouse with their mind.

Neuralink’s first human patient able to use mouse…:

Elon Musk is the visionary behind Neuralink. He announced that the first human recipient of the company’s brain chip implant has fully recovered. The individual has demonstrated the ability to use a computer mouse solely through thoughts. Watch this video for all details.

Researchers have unraveled how mutations in a gene can lead to an incurable neurodevelopmental disorder that causes abnormal brain development in newborns and infants.

The WEHI study is the first to prove that a protein called Trabid helps control neuronal development, and that mutations to this protein can lead to microcephaly —a condition where a baby’s brain is smaller than expected.

It’s hoped the milestone findings will provide a deeper understanding into the protein’s impact on healthy development and lead to treatments that can slow or stop the development of microcephaly and potentially other neurological disorders.

The somatosensory cortex is a brain region known to play a role in the detection of tactile information, changes in temperature, and pain sensations. Some recent studies found that this crucial brain region is also involved in the human ability to learn and retain new motor skills.

Despite initial findings hinting at the involvement of the somatosensory cortex in motor learning, the nature of its involvement remains poorly understood.

Researchers at University of Pittsburgh Brain Institute recently carried out a study aimed at better understanding the contributions of the somatosensory cortex to the learning and retention of new movements. Their findings, published in Proceedings of the National Academy of Sciences, suggest that the somatosensory cortex could be specifically responsible for encoding new sensory targets or, in other words, learning-adapted sensory states.
