There was an error in Development (2018) 145, dev164988 (doi: 10.1242/dev.164988).
It was brought to the authors’ attention that cortical structures bearing GFP::PHPLC1δ1 have been reported in Nakayama et al., 2009 (Figure S7). The authors apologise for not having been aware of this and, therefore, for not having referred to that report in their recent publication.
The authors apologise to readers for this mistake.
