A recent study by Mount Sinai researchers discovered that certain neurons in the brain's decision-making centers monitor body-state dynamics and hijack the decision-making process during intense states of arousal. This suggests that changes in heart rate and other bodily responses can impact the brain's ability to make rational decisions.
The Daylight Award 2022 is now open for nominations, honoring groundbreaking research on the effects of daylight on human health and well-being. The award also recognizes innovative architectural projects showcasing unique uses of daylight, aiming to improve living conditions and environmental impact.
Researchers found increased capillary blood flow in mice brains during REM sleep, indicating a possible role of adenosine A2a receptors in brain refreshing. This unique state may be crucial for waste removal from the brain, which is associated with Alzheimer's disease development.
Chronic light exposure disrupts circadian rhythms in rats, leading to memory deficits and amyloid β accumulation similar to Alzheimer's disease. Fluoxetine treatment prevents these effects, suggesting a potential therapeutic strategy.
Researchers developed a 'sensing leg' with sensors that detect pressure and movement, enabling users to navigate obstacles more efficiently. The system also includes a neuro-pacemaker mode that stimulates remnant nerves, reducing phantom limb pain and improving overall well-being.
A new study developed a wearable technology-based method to assess myoclonus symptoms in the home environment. The method, which measures electrical neuromuscular function and movement, correlates well with assessments performed by experienced physicians.
Researchers use X-rays to activate opsins in neurons, allowing for remote control of neural function and behavior. Scintillators emit visible light in response to X-ray irradiation, enabling the technique without tissue damage.
Researchers have discovered distinct populations of neurons in the mesencephalic locomotor region that control different body movements. These findings could improve therapies for Parkinson's disease by targeting specific neuronal populations involved in postural changes and body extension.
A research team at Toyohashi University of Technology has developed a lightweight, compact, Bluetooth-low-energy-based wireless neuronal recording system for use in mice. The system weighs less than 3.9g and offers high signal quality, good versatility, and low cost compared to wired recording.
Research reveals distinct brain regions process concrete and abstract word meanings separately, with a network of areas working together in different languages. The findings provide new insights into how our brains represent word-meaning structure.
Researchers at Cornell University found that mosquitoes can detect sound waves from distances of up to 10 meters, including human speech and the buzzing of female mosquitoes in flight. This discovery could lead to the development of more sensitive directional microphones and hearing aids.
A study of 154 individuals with near-death experiences found that while common phenomena like feeling peacefulness and seeing a bright light occur frequently, the order of appearance varies greatly between participants. The most commonly reported sequence was out-of-body experience followed by a tunnel, bright light, and finally peace.
Dr. Donald Schomer, a Harvard Medical School professor, is recognized for his pioneering work in comprehensive epilepsy programs and training fellow clinicians worldwide. He has trained 46 fellows since establishing the fellowship program at Beth Israel Deaconess Medical Center.
The American Academy of Neurology recommends monitoring the spinal cord during spinal surgery and certain chest surgeries to prevent paralysis. Intraoperative monitoring can alert surgeons to potential problems before damage occurs, reducing the risk of complications.
A new study published in Neuron found that the brain can split attention into multiple 'spotlights' when focusing on two or more objects. This challenges traditional views on multitasking and suggests a more efficient way of processing information.
A Barrow researcher has received a $120,000 grant to study flicker fusion and its impact on people with epilepsy. The goal is to develop safe brain products that can make artificial lighting appear stable to the brain.
