Erratum to: ‘Purkinje cell injury, structural plasticity and fusion in patients with Friedreich’s ataxia’

Erratum After publication of this study [1], we discovered that the unit of measurement used to quantify changes in axonal morphology had been incorrectly labelled. Both the methods section ‘Purkinje cell axonal morphology’ and ‘Table 2 legend’ should read:All axonal changes are expressed as either frequency per standardized unit length of the Purkinje cell layer (1 centimetre) or frequency per Purkinje cell.
