Summary of neural codes.
Neural code | Outcome |
---|---|
1. Firing rate of individual afferents (SA1, RA, PC) | Rejected because individual rate-intensity functions comprise long entrainment plateaus. |
2. Firing rate of afferents of a given type whose RFs are located in the “hot zone” | SA1, R2 = 0.68 RA, R2 = 0.89 PC, R2 = 0.74* |
3. Firing rate of afferents whose RFs are located in the “hot zone,” weighted by type | R2 = 0.97 |
4. Number of afferents of each type activated in the “hot zone” | Rejected because the number of recruited afferents plateaus at low stimulus intensities. |
5. Estimated total firing rate of afferents of a given type | SA1, R2 = 0.56 RA, R2 = 0.80 PC, R2 = 0.74* |
6. Weighted total estimated firing rate across afferent types | R2 = 0.96 |
7. Estimated number of active afferents of each type | SA1, R2 = 0.10 RA, R2 = 0.51 PC, R2 = 0.54 |
8. Estimated weighted number of active afferents | R2 = 0.86 |
Codes are computed identically due to the nature of PC RFs.
