Scientists map gene activity in brain's prefrontal cortex
KSL.com • • health
Key Points:
- Scientists have created a detailed gene activity map of the prefrontal cortex, offering new insights into normal brain development and disorders like Alzheimer's, Parkinson's, and schizophrenia.
- The study analyzed over 6.3 million brain cells from 1,494 donors aged from infancy to 108 years, including individuals with various brain disorders and diverse genetic backgrounds.
- Researchers identified shared and disorder-specific gene activity patterns, highlighting vulnerable cell populations and biological processes that could guide targeted treatments.
- The research revealed that gene activity stabilizes around age 24, with notable changes during development and later life, and found links between genetic risk factors and specific brain cell types.
- Findings also showed altered daily gene activity rhythms in older adults and biological differences among individuals with Alzheimer's, suggesting avenues for personalized therapies and future research on brain health.
