Description
Seyed Javad Saghravanian and Hossein Esteky tested, in a 2025 study, whether mild brain stimulation sharpens face recognition. The method passes a weak current through the scalp over the brain area that handles faces. Volunteers matched morphed faces that ranged from easy to near-identical.
Forty-seven people were split among three active layouts and a sham group. One layout, with the positive pole on the right face area and the negative on the left, beat sham clearly. Gains peaked on the most ambiguous faces, near the point where two faces feel equal. Reaction times grew longer under stimulation in all active groups. The early results hint at a side bias in face identity work, though the sample was small.
