How can I differentiate between the cerebral cortex, cranial layer, cerebrospinal fluid, gray matter, and white matter layers using a single fNIRS dataset?

Hello everyone,

I hope you’re all doing well. I’m trying to distinguish between the cerebral cortex, cranial layer, cerebrospinal fluid, gray matter, and white matter layers using a single fNIRS dataset. Specifically, we are using Time-Resolved fNIRS (TR-fNIRS). I would appreciate any advice or suggestions on how to achieve this.

Thank you in advance for your help!

Best regards,
Xie
