Figure 2. Overview of Training Sessions.

Figure 2

Two training sessions were conducted every week at the home of the patient. A total of 357 runs (with tasks that were 2 to 5 minutes in duration) were performed in 67 sessions. Shading indicates the types of tasks that were performed. Spelling was attempted in week 8, but the patient reported that excessive mental effort was required. Better decoding enabled spelling starting from week 25. Arrows with the same shading as the bars indicate the time at which parameter settings for the respective task were established, marking the onset of actual training on the task. The ball task was used only for parameter adjustment and was not subsequently used for training after the parameter settings had been fixed.
