Table 3.

Correlation coefficients relating the estimated duration of neural activity to the actual delay-period duration (interval between beginning of each trial and the end of the behavioral response period). Asterisks indicate a significant positive correlation and evidence for rejecting the null hypothesis of no sustained activity during the delay period
