A. Cartoon of ordering effect indicated by honeybee descending neuron responses. Spatial frequency decreases from blue to green. B. Model diagram showing annealed synapses (coloured, same colours indicate same synaptic conductance). C. Slice of annealing results (Medulla-Lobula conductance of 0.04nS) showing stable region (green / blue area). D. Model response for a high objective function value (left), and the corresponding response for an RHD using the model output up to the Medulla.
