Study identifies a different set of individual neurons in the medial frontal cortex that is responsible for memory-based decision making. The findings have implications for the treatment of Alzheimer's disease, schizophrenia, and other disorders associated with problems in cognitive flexibility.
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.
Artificial intelligence technology is able to break down a painting's visual attributes. Trained by data from online users, the deep convolutional neural network was accurately able to predict an individual's taste in art.
According to researchers, people are able to judge whether a politician has been convicted of corruption just by looking at their faces.
Using germ-free mouse models, researchers transplanted fecal bacteria from children on the autism spectrum and neurotypical children. Mice who received the transplants from the ASD cohort began to exhibit autism-like behaviors, whereas the mice who received transplants from typically developing children did not. Additionally, the mice showed altered gene expression in their brains and differences in types of metabolites present. In particular, the ASD mice had lower levels of 5AV and taurine. Findings suggest gut microbiota regulates autism-like behaviors via the production of neuroactive metabolites, providing further evidence for the gut-brain axis connection to the pathology of autism.
Hard wired neural circuits in mice that govern aggression are strengthened following victories in aggressive encounters. Synapses in the hypothalamus show signs of LTP following aggression training.
