Fig 7. Amount of information in neuronal and voxel populations with diverse forms and strength of NCs.

Fig 7

The upper and the bottom rows depict the amount of information as a function of increasing strength of NCs and the increasing number of units in the population, respectively. Panels A-C and F-H illustrate the amount of information in a neuronal population and correspond to Fig 4. Panels D-E and I-J illustrate the amount of information in a voxel population and correspond to Fig 5. Note that here we only illustrate the information in the stimulus-estimation task. We consider three types of NC—aTCNC (panels A, F), cTCNC (panels B, G), and SFNCs (panels C, H) in the neuronal population, as already shown in Fig 4. Similar treatments are performed for the voxel population, as shown in Fig 5. The calculation of information largely mirrors the decoding results shown in Fig 4 and Fig 5. Critically, the amount of information in the voxel population exhibits U-shaped functions of increasing strength of cTCNCs (panel D) and cTCNCs do not limit information as the number of voxels increases (panel I). These results clearly differ from the effects of aTCNCs (panels A, F) and cTCNCs (panels B, G) in the neuronal population.
