Newly designed microbots can deliver vital drugs throughout the human body. The microbots can traverse the body and penetrate bodily mucus to efficiently deliver medications to target sites.
Researchers have developed a new test that examines theory of mind in those on the autism spectrum. The work may shed light on how those with ASD have difficulty in understanding the point of view of others, and social behavioral deficits.
Serotonin produced by the raphe is critical for sleep in both mice and zebrafish. The firing of neurons in the raphe and the release of serotonin may help the brain build up better sleep pressure. The results may explain why some sleep-related side effects of antidepressants increase serotonin in the brain.
Researchers identified the gut bacteria E. faecalis as a mediator of social behavior and corticosterone levels in mice.
Neurons in the anterior intraparietal cortex learn to modulate their activity to compensate for errors in brain-machine interface tasks. Findings suggest the extent to which a person can learn a new skill is constrained by preexisting neural networks.
Study identifies rare brain cell types that are unique to male mice, and others that are unique to females. The cells were discovered in the hypothalamus, a region of the brain that governs both aggression and mating behaviors.
