Overview of the different functional conditions used in this study

Condition name	Condition description	Condition duration	No. of repetitions of each condition	Visual cue indicating each condition	Event-related contrast vectors for the GLM design matrix of the first-level analysis
REST	Visual fixation	15–18 s*	min. 16×		Not modeled
IMITATE	Subjects visually imagine starting to micturate	6 s	min. 8×		IMITATE, 6 s
INITIATE	Subjects attempt to initiate micturition	Variable, max. 60 s	min. 8×		INITIATE early, 3 s
					INITIATE late, 3 s
URINATE	Actual micturition; urine is flowing	3 s	As often as possible	No cue presented; start of URINATE condition was determined by start of urine flow detected by the flow detector	URINATE, 3 s
STOP	Stop micturition	3 s	Only following successful URINATE		STOP, 3 s

Notes: The conditions URINATE and STOP, were only applicable if micturition could be initiated. In nonvoiders, the INITIATE condition was always followed by the REST condition of the subsequent block.

*REST conditions following INITIATE (in the case of inability to initiate micturition) or IMITATE had a duration of 18 s. REST conditions following STOP had a duration of 15 s.
