Results for self-organization experiment.

Population summary statistics of response properties of output neurons in the model at three different stages of training. Results for the untrained model are shown in the left two columns, results for the model after epochs of training are shown in the middle two columns and the results for the model after epochs of training are shown in the rightmost two columns. For each stage, results are presented in two subcolumns: statistical measures computed over all output neurons are shown in the left subcolumn, while measures computed over neurons with a receptive field index greater than zero indicating head-centered responses are shown in the right subcolumn. Each row corresponds to a different performance metric: head-centeredness, eye-centeredness, receptive field index, head-centered receptive field location, and head-centered receptive field size. Each cell of the table shows the mean and standard deviation (in parentheses) of the peformance metric over the relevant population of output neurons.
