Author response image 1. Similar expression of Pcp4 in the cortical cell cluster across datasets.

Using cortical cells from our dataset (Erwin et al.), we identified the corresponding cluster from the integrated analysis including other published datasets (Saunders t al., Zeisel et al.). Pcp4 expression is illustrated (via dimensionless units, corresponding to integrated scaled data), both for individual cells from each dataset (black dots), as well as associated violin plots on a per-dataset basis (coloured contours).
