Research indicates that autism and ADHD may share common neurobiological mechanisms, with the severity of autism-like traits correlating with specific patterns of brain network connectivity related to cognition and social behavior. The findings suggest a dimensional rather than categorical approach to understanding these conditions, revealing atypical developmental pathways even in individuals without formal autism diagnoses.
Researchers have developed a highly sensitive and selective fluorescent probe for imaging serotonin, which is relevant to understanding depression diagnosis, treatment, and drug development. This tool enables better visualization of serotonin-related biological processes in depression research.
