Learning to reproduce a trajectory. (A) Training trajectory used (thick solid line). Mental recapitulation of the bump trajectory after a single trial learning (dots, spaced at 0.2-s intervals). The dots are calculated as the spatial center of gravity of the firing rates of all place cells in area E. (B) The spatial trajectory of the RR in following the mental trajectory (thin solid line). The rate of adaptation has been decreased by a factor of 2 from that in A so that the mental trajectory is generated more slowly and the motor system can follow better.
