‘Residual echo’ of ancient humans in scans may hold clues to mental disorders

Researchers have produced the first direct evidence that parts of our brains implicated in mental disorders may be shaped by a ‘residual echo’ from Neanderthal DNA in our genomes. Evidence from MRI scans suggests that such ancient genetic variation may affect the way our brains work today — and may hold clues to understanding deficits seen in schizophrenia and autism-related disorders.
