Independent of IQ, decision acuity predicted performance in decision-making tasks. This factored higher in older adults and increased in light of parental education.
Inspired by techniques to train deep neural networks, researchers have proposed a new hypothesis of dreaming. The hypothesis suggests the strangeness of our dreams may help our brains better generalize our day-to-day experiences.
Noradrenaline impairs immune response by inhibiting the movement of leukocytes to different tissue.
It is well-known octopuses change their color while they sleep. A new study reveals the color changes characterize two distinct sleep states, "active sleep" and "quiet sleep". The findings shed new light on the evolution of sleep.
Astrocytes derived from pluripotent stem cells of bipolar patients provide suboptimal support for neural activity. The malfunction can be traced to the inflammation-promoting molecule, interleukin-6.
During REM sleep, people are able to interact with researchers and engage in real-time communication. The study reports while dreaming, people can follow instructions, perform simple math, answer yes and no questions, and tell the difference between different sensory stimuli.
Researchers report α-actinin-3 deficiency improves cold tolerance in humans by increasing muscle tone. Approximately 1.5 billion people worldwide are believed to have this deficiency.
A new two-stage model seeks to answer a longstanding philosophical debate over whether consciousness is continuous or discrete. Findings suggest discrete consciousness is preceded by a long-lasting unconscious processing period.
Friends who "swapped bodies" using virtual reality to generate the perceptual illusion found their beliefs about their personalities altered to become more similar to the beliefs about their friends' personalities. Findings suggest that when our mental self-concept doesn't match our physical self, our memories become impaired.
Cholesterol-lowering statins show promise for the treatment of severe coronavirus infections. Statins lowered the death rate and decreased the need for mechanical ventilation in patients hospitalized for severe COVID-19.
Adult born neurons are essential for synaptic structural remodeling and memory consolidation during REM sleep, a new mouse study found.
Smoking increases the gene expression of ACE2, a protein that binds to SARS-CoV-2, increasing the risk of coronavirus infection. Findings suggest long-term smokers could have an increase of ACE2 in the lungs, leading to higher rates of morbidity in COVID-19 patients.
