Those with dark triad or antagonistic personality traits including narcissism, Machiavellianism, and psychopathy are more likely to endorse negative beliefs about others, especially the LGBTQA+ community. People with these personality traits adopt prejudicial beliefs as they downplay the importance of equality and show little interest in protecting others, researchers conclude.
Healthy microbes in the gut encourage synaptic pruning in brain circuits associated with social behavior. Previous research has linked both poor synaptic pruning and gut health to neurodevelopmental disorders including ASD. The new findings could pave the way for treatments for disorders associated with social behavior deficits.
A new map of the octopus visual system classifies different types of neurons in a part of the brain dedicated to vision, shedding new light on the evolution of the brain and visual systems in a more broad sense.
Mutations to the EGR1 gene disrupt social behaviors in zebrafish models of ASD. Additionally, the mutation disrupts dopamine signaling from specific neurons, contributing to mood and social behavior disorders.
Distinct, coordinated activity in large sets of neurons can predict the future behaviors of rats, a new study reports. Based on the findings, researchers have created a "dictionary" that links brain activity patterns to simple behavioral outcomes.
Overall, restrictive eating was the only feeding practice that linked parent and child emotional eating.
Astrocytes help transition the brain from a highly plastic state to one that is more stable.
Dendrites weave their way through space that balances their need to connect to other neurons, but there is a cost.
Children as young as three have an adult-like preference for visual fractal patterns commonly seen in nature. The findings suggest the preference for common natural fractal patterns develops early in life.
