Orientations for the successful categorization of facial expressions and their link with facial features.

abstract：:Eye movements are the most frequent (∼3/s), shortest-latency (∼150-250 ms), and biomechanically simplest (one joint, no inertial complexities) voluntary motor behavior in primates, providing a model system to assess sensorimotor disturbances arising from trauma, fatigue, aging, or disease states. We have developed a 1...
