Correction to: The sensitivity of event-related potentials/fields to logopedic interventions in patients with stroke-related aphasia (Acta Neurologica Belgica, (2020), 120, 4, (805-817), 10.1007/s13760-020-01378-3)

Abstract

In the above article, the citation numbers in Tables 1 and 2 are referring to wrong references. The corrected tables can be found attached. Moreover, in Table 2, the time-windows for citation numbers 53 (Becker & Reinvang, 2007), 61 (Breier et al., 2007) and 62 (Woodhead et al., 2017) are corrected (Tables 1 and 2). (Table presented.)
