Figure 1.

Overview image of the Computer Aided Design (CAD) data. The design of the Neurite Outgrowth Chamber (NOC) includes an inlet for drug delivery into the ST-compartment. Via the canal, those drugs can diffuse into the RC-compartment, housing the spiral ganglion explants (SGEs). (A) The position and angle (45°) of the inlet in the ST-compartment is illustrated in the side view of the NOC. (B) Both compartments and the inlet are presented in an oblique view. (C) The marked 10 mm distance represents a fivefold increased average of the reported distance of about 2 mm between the RC and a cochlear implant electrode in human cochleae (top view). (D) A rear view depicts the 3 mm height of the NOC. Dimensions in the drawing are given in mm.
