Extended Data Figure 3. Trained animals can adjust amplitude to changing task requirements.

A) Reach amplitudes from a sample of 7 sessions in 2 mice in which the eccentricity of the threshold to receive reward was suddenly increased at random. Green field identifies reaches performed with the increased amplitude threshold. Shaded area represents standard error of the mean. B) Success rate before (black) and after (green) the jump in amplitude threshold. C) Distribution of reach amplitudes across sessions for pre- (green) and post- (black) amplitude threshold jump. These data indicate that the mean amplitude was not saturated and suggest that behavior remains outcome dependent (i.e. goal-directed).
