Both bony fish and sharks have multiple chemosensory systems, and they have chemosensors in a variety of locations including oral-esophageal regions, in the paired olfactory organs (nares), and occasionally on external body surfaces such as the barbels of catfish (Derby and Sorenson, 2008; Yopak and Frank, 2009; Meredith and Kajiura, 2010).
The chemosensory inputs that mediate RRLH in mice are detected by the vomeronasal organ, and relayed via the accessory olfactory bulb, and the vomeronasal amygdala, to the hypothalamic gonadotropin releasing hormone (GnRH) neurons.
The research has been made available in the Springer journal Chemosensory Perception.
The important message is not to ignore chemosensory loss, even if it is manageable to live with.
Searching chemosensory behavior appears to be initiated when cephalic tentacles extend and retract, whereas the epipodial tentacles are likely distance chemosensory sensors.

Very little is known about chemosensory information processing beyond the level of receptor neurons.
When borrowed by resistant consumer species, however, they confer chemical defense against higher-order predators or operate in chemical communication as chemosensory excitants (Brown, 1984; Kvitek and Bretz, 2004, 2005; Williams et al.
