Figure 3. Progenitor cell proliferation and survival in the olfactory bulb.

Figure 3

There were no effects due to photoperiod in progenitor cell proliferation 2 h after BrdU injection (A,C,E,G). Exposure to short days increased progenitor survival in the posterior olfactory bulb (H). The majority of these differences were in the posterior plexiform and granule cell layers (F), whereas there were no differences due to photoperiod the medial (D) or anterior (B) olfactory bulb. All abbreviations after Paxinos & Franklin (2004): Gl, glomerular layer of the olfactory bulb; IPl, internal plexiform layer of the olfactory bulb; EPl, external plexiform layer of the olfactory bulb; GrO, granule cell layer of the olfactory bulb. *p≤0.05.
