The inner voice used for thought has a specific neurobiological basis
the verdict
SUPPORTED
the evidence backs this
confidence 83/100
Multiple neuroimaging and brain-computer interface studies confirm that inner speech has a distinct neurobiological basis, showing robust representations in motor and auditory cortical networks that can be measured and decoded.
