Fig. 2: Memory accuracy. Memory accuracy for all trials and for each difficulty level (L1, L2, and L3) is shown for the personalized TMR, TMR, and CNT groups.

In the top row, the light-colored bars represent pre-sleep session accuracy and the dark-colored bars represent post-sleep session accuracy. The bottom row displays the difference in accuracy between the pre-sleep and post-sleep sessions. Significant differences (two-sample t-tests with Bonferroni correction, p < 0.05) are marked with asterisks.
