Figure 7.

Decoding accuracy of NAs and random neurons. In black, we show the decoding accuracy using solely neurons from the NAs identified with ICA; in blue, the same cells were used but labels of animal response (left/right) are shuffled. In red, we use a random group of neurons out of the total population, containing the same number of cells as the identified NAs. We recall that no further restriction is imposed, i.e., the selection of cells belonging to other NAs, which also significantly modulate their firing rate, is possible. The shuffling process was repeated 100 times. In green, we depict the moments in which the decoding accuracy in NA and random cells are significantly different (p < 0.05). Time t = 0 s marks the moment rats reach the NP. Dashed blue (red) vertical lines indicate the approximate beginning of trials (reward) time.
