Erratum to: J Neurol DOI 10.1007/s00415-012-6567-6

This original publication of the article contained errors owing to oversights in editing and typesetting. (1) In the second paragraph of the section “Direct evidence for the role of ICAP-1 in preventing excessive vascular growth”, the word “inconclusive” was incorrectly changed to “conclusive”. (2) The two reference citations in Figure 2 legend were wrong: the correct references are numbers 67 (not 68) and 42 (not 43). The publisher and authors sincerely apologize for these errors.
