Piriform cortex (PC) neurogenesis. (A) The upper part shows the olfactory sensory pathway. The olfactory bulb transmits the signal to the PC as the first relay, and then to other connected regions such as hypothalamus, entorhinal cortex, and amygdala. The lower part of the figure shows the neurogenic sites including the hippocampus and subventricular zone (SVZ). The SVZ gives birth to new neurons in the olfactory bulb and PC through rostral and caudal migration streams. (A was modified from Klempin et al., 2011). (B) The doublecortin (DCX) staining in the PC (coronal section). Scale bar: left: 200 μm, right: 50 μm.
