The MSNs and UINs identify contextual information significantly better than the FSIs. A, Neurons were able to modulate their firing in relation to the environmental identity and not the animal's locomotion. The number of gridline crossings in 5 s bins (pink line) overlaid over firing rate histograms calculated in 5 s bins of an exemplary UIN. B, The UINs and the MSNs identify contextual information significantly better than the FSIs. Distribution of SVM accuracy values for 3000 repetitions of random selection of n = 21 MSNs (red) or FSIs (blue). The accuracy value obtained using all the sampled UINs (n = 21) is shown in cyan.
