Specificity of learning. a. The coherence dependence of the sensory information (a in Eq. 4) estimated from behavioural performance from sessions 30–50 for monkey Z. The solid line is a 21-session running average. b. The difference between the coherence dependence from a given session and its 21-session running average for behaviour (black), MT (cyan) and LIP (red) responses are plotted against the absolute z score of motion direction for monkeys C (top) and Z (bottom). For a given session, the z score is computed using the distribution of motion directions used prior to that session. Thus, less frequently used motion directions will have larger z scores. Solid lines are linear fits.
