Extended Data Fig. 1: Histology from three additional recording sites.
From: Large-scale single-neuron speech sound encoding across the depth of human cortex

Each Nissl stain is from fixed tissue that was sectioned to cover the region immediately surrounding the Neuropixels insertion site. Attempts were made to localize the insertion site, but this was very difficult to do with standard anatomic pathology sampling. Therefore, we have provided images from approximately the same area.
