Performance Analysis. A: Example turn sequence made by a CTR rat and the expected sequence of alternating left and right turns. B: Performance matrices of observed and ideal sequences. Rows represent the previous turn and columns represent the current turn. Rows are normalized to sum to one to account for varying session lengths. C: F is the sum of squares of the difference between the observed and expected performance matrices. The rat’s score S is calculated relative to the best performing rat.
