Number of videos for Th^2A-CreER and Drd2^Cre;GCaMP6f mice by category. Individual cells represent the number of videos or mice as defined by the leftmost column for the condition described in the topmost row. Videos for Th^2A-CreER;GCaMP6f were taken from apical sections of the cochlea, whereas videos from Drd2^Cre;GCaMP6f are from basal sections of the cochlea. Videos recorded when the tissue is bathed in external solution without the presence of PPADS are designated external and ones with PPADS in the bath are designated as PPADS. NGAF refers to NGAF. To calculate the neuronal response rate, take the value of # photoablation with neural response and divide it by the sum of the values for # photoablation with neural response and # photoablation without neural response. To calculate the NGAF response rate, take the value of # with NGAF and divide it by the sum of the values for # with NGAF and # without NGAF.
