Responses obey a single mean–variance relation across behavioral conditions in a TE neuron. x-, y-axes, Mean and variance of number of spikes elicited by each stimulus on a logarithmic scale. Log(mean) versus log(variance) for each of three task conditions in a single TE neuron. Sample,Red squares; nonmatch, blue circles; match,green triangles. Regression lines for individual conditions are shown in the corresponding colors, extended to the edges of the plot for visibility. The regression line for all conditions together is shown in black. Colored bars at the bottom show the range of means for each task condition (sample, nonmatch, and match). The neuron shown has the median p value for thef test comparing the model using a single regression line to the model using three regression lines.
