Notes
- It is not because a particular stimulus_source is used in a given timeline that all possible stimuli of that source are displayed to the user. For example, the AX-CPT may use "upper-case-letters" but only use a subset of those letters (e.g., "A", "B", "X", "Y"). Whenever possible, we specify the most relevant/specific set (e.g., "digit1to9" rather than "digit").
