Figure 5. — Odor exposure increases number of excitatory MC responses. A--D, Ratio of above-threshold excitatory responses to all odor presentation trials across odorants. Odor-exposure groups had significantly higher ratio of excitatory responses as compared to control groups for odors at 1% concentration (A) and multiple concentrations (B--D). E, MCs in all groups responded to a high number of odorants (median number of odorants: control, 13; mint exposed, 14; hexanal exposed, 14). Gray asterisk, statistically significant difference between mint and control groups; blue asterisk, statistically significant difference between hexanal and control groups.
