Attractive and aversive odor representations are partly separated in the MB calyx. a Hierarchical cluster analysis for 17 odors based on the correlation distances between the functional maps. The cut-off threshold is set at 0.6 linkage distance, detecting two groups of separately clustered odors colored in red and cyan. b A complete correlation matrix for 17 odors based on the similarities of functional maps in the MB calyx between each odor. Each axis of the matrix is ordered as in a. c The virtually reconstructed functional maps in the MB calyx are visualized two-dimensionally in the anterior view (top) and the horizontal view (bottom). Color map is scaled for each image to represent the maximum range
