Figure 1. 3D computed tomography [CT] reconstructions of electrode array placement.

Figure 1

(A) Posterolateral view of 3D CT surface reconstruction showing electrode array leads implanted in the left labyrinth of a rhesus monkey via the mastoid cavity. a: lead to anterior and horizontal ampullae; b: lead to posterior ampulla; c: common crus reference electrode; d: neck reference electrode; M: mandibular ramus; Z: zygomatic arch; ANT, POST, SUP, INF: anterior, posterior, superior, inferior. (B) Oblique CT cut through the plane of the basal turn of the cochlea [Co], showing bifurcated electrode array [a] entering the ampullae of the superior [s-scc] and horizontal [h-scc] semicircular canals. Part of the neck reference electrode [d] is also visible, but the posterior scc electrode array is not included in this section. AM, PL: anteriomedial, posterolateral.
