Mouse Auditory Cortex (IMAGE) Cold Spring Harbor Laboratory Caption BARseq demonstrated in the auditory cortex of a mouse. Purple staining showed which neurons host activity of a specific gene (Fezf2). Green staining indicated the presence of a barcode label and show which neurons are communicating. Combined, this information helps neuroscientists classify neuronal types. Credit Zador lab/CSHL, 2019 Usage Restrictions Attribution needed.
