Direct Connections Found Between Areas of Brain Responsible for Voice and Face Recognition

Face and voice are the two main features by which we recognise other people. Researchers at the Max Planck Institute (MPI) for Human Cognitive and Brain Sciences have now discovered that there is a direct structural connection consisting of fibre pathways between voice- and face-recognition areas in the human brain. The exchange of information, which is assumed to take place between these areas via this connection, could help us to quickly identify familiar people in everyday situations and also under adverse conditions.

Direct structural connections exist between the two voice recognition areas (blue and red spheres) and the face recognition area (yellow sphere). In comparison, the connection to the area responsible for more general acoustic information (green sphere) is less strong. The connections appear to be part of larger fibre bundles (shown in grey).
