📊 AGE-RELATED PATTERNS:

Research shows DHEAS peaks in your 20s, then declines approximately 1-2% yearly after age 30 (Samaras et al., 2013). This well-documented decline has been studied in relation to various aspects of aging.

The non-invasive nature of #fNIRS, combined with the Brite's wearability, enables Dr. Gonzalez’s team to conduct research on neurocognitive aging in comfortable settings, such as a retirement home.

In this interview, Dr. Gonzalez shares her insights and discusses how fNIRS is advancing our understanding of how aging influences brain function and behavior. https://www.artinis.com/blogpost-all/fnirs-to-research-neurocognitive-aging

Humans think they're clever with their "cat years" calculations, but turns out their own aging isn't so linear! 🤔 Scientists discovered dramatic molecular changes hit in mid-40s and early 60s. So your reduced caffeine tolerance isn't just you being dramatic - it's science! 🧬 At least you can still nap like a pro. #AgingScience #Science
