Classification of stimuli by the VNO. A, Firing rates of 64 VNO single units collected from female mice (n = 12) responsive to at least one stimulus at p < 0.05. B, Classification success rate as a function of cell pool size (k = 5, LDA dimensions 1–7). Black line, Success rate across all stimuli (4M+4F); blue line, success rate when distinguishing only among male urine stimuli (4M); red line, success rate when distinguishing only among female urine stimuli (4F). C, D, First two and three LDA projections of best 25 cells in the VNO data set. LD1, LD2, and LD3 are the LDA directions 1, 2, and 3, respectively. E, Classification result matrix (confusion matrix) for best 25 cells in the VNO [k = 5, LDA dimensions 1–7; vertical axis, patterns presented; horizontal axis, patterns predicted (classified)]. F, Classification matrix for all 64 cells. RC, Ringer's control.
