Theoretical Analysis of Pre-Receptor Image Conditioning in Weakly Electric Fish

Figure 2

Image Generation in a Fish with Internal Conductivity like That of Water and with a Homogeneous Highly Conductive Skin

The black bars show the zero equipotential surfaces as in Figure 1.

(A) Basal field (in the absence of objects). (B) Perturbing field produced by the same scene as in Figure 1B.

(C) Electric image of the metal object depicted in a colour map on the modelled transparent fish from a scorci view.

(D) Electric image along the intersection of the skin with the sagittal plane.
