Case study: Where do aphasic perseverations come from?Footnote

We are grateful to MM for agreeing to participate in this study, which formed part of the first author's postgraduate study at the University of York, supported by a major scholarship from the Hospital Saving Association Charitable Trust, and by the Leeds Community and Mental Health Trust and the Leeds East Primary Care Trust.
