In the article “Deciphering the Spike Train of a Sensory Neuron: Counts and Temporal Patterns in the Rat Whisker Pathway,” by Ehsan Arabzadeh, Stefano Panzeri, and Mathew E. Diamond, which appeared on pages 9216–9226 of the September 6, 2006 issue, the Figure 3 that printed was not the correct version of the figure. Some gray shading was mistakenly accentuated. The corrected Figure 3 is printed here.
Figure 3.
Spike count information. A, Cumulative information carried by the cortical cluster during presentation of stimulus pair CD–P280 (left) and the total stimulus set (right). To highlight information accumulation in relation to the whisk cycle, the protraction phase is shaded. In this and all figures, time steps were 1 ms. B, Cumulative information carried by the ganglion cell during presentation of stimulus pair CD–P280 (left) and the total stimulus set (right, solid line). During the protraction phase (shaded), the cell carried no information. A second ganglion cell carried information only during whisker protraction (right, dashed line). C, Correlation between ganglion and cortex spike times (top trace), and correlation between the rate of ganglion and cortex information flow (bottom trace). D, Matrix of all pairwise information values for ganglion (top left) and cortex (bottom right). Circles indicate the stimulus pair P400–P1200. Note the different information scales for the two plots.
