^§defined by microscopic evaluation of serial 14 µm cryostat sections.

^δtwo or more PLAP+ cells in a location earned a positive score (checkmark). HJ are author initials followed by the unique specimen identification code.

^ψPLAP+-cells were most frequently detected in the base and middle turn of the cochlea and rarely in the apex.
