| Abstract(in English) | Recent findings about an activation of the dorsal premotor area (PMd) during observation of smooth biological movements suggest that this motor-related area detects biological motions. We hypothesize that a neural network in the PMd acquires an invariance of biological motions from time-series motor commands self-movements and thus interprets the observed smooth trajectories as biological ones based on the invariance. Our simulation shows that predictive learning allows a recurrent neural network to represent the invariance of biological kinematics and thus to detect the biological motions. This result agrees with the fact that the PMd originally functions as a motor predictor. We also show that this neural network can recognize the ankle and wrist trajectories of walking human as biological regardless of the subject's sex and emotional state. |
