Fig. 5. The effect of odor exposure on the olfactory bulb. (A) The odor exposure increases the number of total cells, neurons, and proliferating cells, and reduces the ratio of non-neuronal to neuronal cell numbers (indicated as “cellular constitution”). *p<0.05, ***p<0.001. (B) Representative immunofluorescence images captured from the rostral migration stream of treated and control mice show the distribution and density of DCX-positive (red) and Ki-67-positive (green) cells. Arrowheads indicate Ki-67-positive cells. The scale bar in the last image applies to all other images.
