olfactory bulb
Acronym: OLB
The term olfactory bulb refers to a structure that mediates the second level of sensory information processing in the olfactory system ( Buck-2013 ). It has two variants: the main olfactory bulb (OLBm) and the accessory olfactory bulb (OLBa). One or both variants are found in the human ( Buck-2013 ), macaque ( Price-1990 ), rat ( Swanson-2004 ) and and mouse ( AMBA-2024 ). The two variants are embedded in the same OLB structure.
      Neurons in the olfactory bulb have receptors for testosterone, and destruction of the bulb greatly reduces male sexual behavior in the rat ( Cunningham-2012 ). They also have receptors for estrogen and progesterone ( Abaffy-2023 ).. So, the OLB presumably adds information as to the sex and sexual receptivity of the perceiver to the sensory signal that it transmits to the third signal processing level of the olfactory system, For more on functions, see main olfactory bulb and accessory olfactory bulb.
