  • The table shows r values from Rayleigh’s test at the different time points for individual cats before and after hemisections for cycles with 1:1 and 2:1 (first and second forelimb cycles) coordination for right homolateral coupling (the phasing between right forelimb and right hindlimb contacts). The r value measures the dispersion of phase interval values around the mean, with a value of 1 indicating a perfect concentration in one direction and a value of 0 indicating uniform dispersion. We performed Rayleigh’s z test: z = nr2, where n is the sample size (number of cycles) and compared the z value to a critical z value on Rayleigh’s table to determine whether there was a significant concentration around the mean (p < 0.05). Asterisks indicate a significant r value. The left column is cat identification (ID). wk = week.
