Notes:
Summary By means of vascular perfusion of the cochlea with K+-free synthetic blood, it is possible to maintain the endocochlear potential (EP) at normal or supernormal levels for periods of 20–42 min. The subsequent decline of the EP is comparatively slow. This is in contrast to the immediate onset and rapid decline of the EP during perilymphatic perfusion with K+-free media. Possible implications of these data concerning the mode of generation of the EP are briefly discussed. It is further shown, that synthetic blood, in which K+ is replaced by Rb+, maintains the EP at normal or near normal levels for 2 h.
