Neuron number coding of stimulus intensity. (A) According to the neuron number coding scheme, there is a higher percentage of laser-responsive neurons in the lateral pathway (SI and VPL) than in the medial pathway (ACC and MD). ***p < 0.001, data are means ± SEM. (B) The relationship between responsive neuron number and stimulus intensity. Significant (ACC, SI, and VPL), or near significant (MD), positive correlations were found in all of the recorded areas.
