Cricket POL-neurons

2) POL-neurons in the central complex:

Using intracellular recording and marking we have found neurons exhibiting the response profiles of compass neurons as proposed by our neural model (see Models and robots / Neural model of compass neurons). These neurons are activated by certain e-vector orientations only and otherwise remain silent (Fig. 7). Unlike the POL-neurons in the optic lobe, no particular e-vector types can be recognized but each neuron seems to represent a certain body orientation relative to the celestial polarization pattern. We propose that body orientation is population-coded by these compass neuron-like cells (publication in preparation; for abstract see below).
