A study of Scandinavian Winter swimmers reveals alternating between cold water swimming and hot sauna sessions may affect the way in which brown adipose fat burns energy and produces heat.
Researchers discovered people with a specific variant of the oxytocin receptor gene OXTR follow more people on Instagram. However, there no evidence was found to suggest gene-environment interactions influence online sociability.
Heart rate synchronization occurs, even when people listen to a story alone, when paying attention to certain points of a story.
Almost half of the identified human accelerated regions of the genome appear to act as neurodevelopment enhancers, researchers say. The findings shed new light on the genetic basis of human evolution.
As potential threats approach, rattlesnakes increase the rate of rattling. The switch to a high-frequency mode makes people think the snake is closer to them than it actually is.
Auditory and speech processing occurs in parallel in the brain, researchers report. The findings contradict the belief that the brain processes auditory information before transferring it into linguistic information.
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.
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.
