Patients characteristics.
Patient characteristics including age at fMRI study date, gender, handedness as described by the Edinburgh Handedness Inventory, time after stroke at fMRI study date rounded to the nearest week, date of admission, i.e. date of infarct, hospital stay including rehabilitation, affected hemisphere, volume of lesion in cubic centimetres, location of lesion, BODS sum of scores at admission and discharge, and compliance.

BODS: Bogenhausener Dysphagia Score quantifies the degree of dysphagia; 1–2: no dysphagia, 2–3: mild dysphagia, 3–5: mild to moderate dysphagia, 4/5–7: moderate to severe dysphagia, 6/7–10: severe dysphagia, and 11–16: profound dysphagia. Compliance refers to the ability to follow protocol and subjects avoided unwanted coughing or throat clearing throughout scanning; please refer to methods for further details. R: right; L: left; M: male; F: female; c: cortical; sc: subcortical; int.: internal; cerebell. hem.: cerebellar hemisphere; art. media: medial cerebral artery; nucl. caud.: nucleus caudatus; ant.: anterior; EHI LQ: Edinburgh Handedness Inventory Lateralisation Quotient. For two patients the compliance data was missing due to pneumatic cushion signal dropout.
