Researchers studying brain volume in chimpanzees and gorillas found that, unlike human brains, these great ape brains do not lose significant mass as the animals grow older. The comparison suggests age-related brain shrinkage seen in humans is not a universal feature of ape aging.
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.
