New brain-machine interface technology allows those who are immobile to control their wheelchairs through mind control. The BMI allows users to traverse natural and cluttered environments after training.
Children have a rapid boost of GABA during visual learning tasks that continue after the training ends. In adults, GABA levels remain consistent. Findings suggest children's brains respond to training in a way that allows the to more quickly and more efficiently stabilize learning.
After eating contaminated food, toxins activate the release of serotonin by the enterochromaffin cells on the lining of the intestinal lumen. The serotonin binds to receptors on vagal sensory neurons in the gut, transmitting signals along the vagus nerve to neurons in the dorsal vagal complex, inducing retching behaviors.
Cocaine use supports the growth of γ-proteobacteria, a common gut bacteria that consume glycine. As glycine levels become depleted mouse models exhibit a higher response to cocaine with abnormal behaviors including increased drug-induced locomotion and drug-seeking behaviors.
Rehearsing positive versions of frequent nightmares before sleep and playing noises associated with positive daytime experiences during sleep helps reduce nightmare frequency, a new study reports.
Eating your largest meal at breakfast time may help decrease appetite for the rest of the day but it does not affect the way in which the body metabolizes calories in a different way to any other meal.
Neurons in the brains of birds are more energy efficient than in mammalian brains.
People who look alike but are not related share similar DNA, a new study reports. The findings also suggest the shared genetic variations not only relate to similar physical appearance but also common habits and behaviors.
Extended intense cognitive work causes potentially toxic byproducts to build up in the prefrontal cortex. This alters control over decision-making, causing a shift toward low-cost actions that require less effort as cognitive fatigue sets in.
A human's ability to interpret the cries of a baby in pain isn't innate but learned from experience.
