摘要

In their response to our article (Haferlach, Wessnitzer, Mangan, & Webb, 2007), Vickerstaff and Di Paolo correctly note that the response function of input units used to evolve our network was the same cos(h_a - h_p) as that used by Vickerstaff and Di Paolo (2005), and resembles the POL neuron arrangement in insects (Labhart & Meyer, 2002) only in the use of three instead of two such units. However it is important to note that our evolved network structure-which maintains a population encoding of the home vector over a set of memory neurons that integrate the input coming from the direction cells-is in fact generalizable to a wide range of direction cell response functions. To demonstrate this point, we here show the results of integrating this network with a very recent model of e-Vector orientation coding in the central complex of the insect brain (Sakura, Lambrinos, & Labhart, 2008).
