TABLE 1.

Stimulation configurations achievable with steered pTP mode using different combinations of α and σ

	σ = 0	0 < σ < 1	σ = 1
α = 0	MP	Basally shifted pBP	Basally shifted BP
0 < α < 0.5		Basally shifted pTP	Basally shifted TP
α = 0.5		Standard pTP	Standard TP
0.5 < α < 1		Apically shifted pTP	Apically shifted TP
α = 1		Apically shifted pBP	Apically shifted BP

The naming convention of a stimulation configuration is based on the hypothesized shift of its excitation pattern. For example, compared to standard pTP mode, apically shifted pTP mode is expected to elicit lower pitch percepts with increasing α
