Figure 1From: Optimizing microsurgical skills with EEG neurofeedbackMean pre-post change in surgical performance time. For Alpha-Theta (AT), SMR-Theta (SMR), and control (C) groups. In contrast to the control group, there is a significant reduction in total time on task as well as in the suture task for the SMR group. Marginal improvement is also seen in overall performance time for both SMR and AT groups. Error bars signify the standard error of the mean (SEM).Back to article page
