We investigated in the rat auditory cortex how each neuron differentially employs the rate coding and temporal spike coding with respect to the space code, i.e., the functional organization. For the first spike latency (FSL) and firing rate (FR), we measured mutual information (MI) against test stimuli, and investigated the distribution of each MI with respect to the tonotopic organization in the auditory cortex. The FSL MI was significantly higher in the high-frequency area than in the low-frequency area, while FR MI did not vary across the frequency axis in the auditory cortex. This result suggests that the temporal spike coding takes advantage of the tonotopic representation to encode the acoustic stimulus information. |
