GoKawiilPsychAD study maps single-cell gene activity in human brain across full lifespan
Researchers analyzed prefrontal cortex tissue from 284 neurotypical donors aged 0 to 97, drawn from the NIMH HBCC and Mount Sinai NIH Neurobiobank collections, to build a single-cell transcriptomic atlas. Donors were screened using neuropathology criteria such as CERAD and Braak scores to exclude Alzheimer's, Parkinson's, schizophrenia, bipolar disorder and cognitive impairment, and were grouped into developmental, young, middle and late adulthood categories.
