AL glomeruli activated by D-limonene odor stimulation via maxillary palps. a A pair of glomeruli DA13 labeled by anti-pERK immunostaining. b Control image without odor stimulation. The bar indicates 100 μm. c Boxplot comparing the brightness of activated glomeruli DA13 in the test (n = 10) with the background brightness in the control (n = 10). Boxplot whiskers are 1.5× interquartile range
