(a). Trajectories of neural firing of fan cell population using only correct (hit) trials for Odour A and Odour 1 and correct rejection (CR) trials for Odour B and Odour 2. The separation and overlap of fan cells were again observed when the incorrect trials were removed from the PC analysis. (b). Trajectories of neural firing of fan cell population using only hit trials for Odour A and Odour 1 and error lick (false alarm, FA) trials for Odour B and Odour 2. Although all of them are trials in which mice made lick responses, similar overlapped representations between Odours-A and 1, and their separation from Odour B were observed, suggesting that fan cells do not simply represent lick-related motor information. (c). Principal component analysis (PCA) for 213 fan cells as in Fig. 2d, but using conjunctive PCA with data from all timepoints (AB-only, T1 – T5). The results show similar A-1 overlap and A-B separation as in Fig. 2d.
