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.
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.
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.
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.
A new model of vertical microbiome transmission between mother and child has been reported. Researchers say microbes in the maternal gut share genes with those in the infant's gut during the perinatal period directly following birth up to a few weeks postbirth.
