| Olfactory modality | The olfactory modality is the sensory modality pertaining to the sense of smell. It usually but not always arises from the stimulation of the olfactory system by chemicals. | ILX:0107962 | 4 | FDI Lab - SciCrunch.org | 01/17/2023 | FDI Lab - SciCrunch.org | term | 12/09/2016 | 0 | NeuroLex | NeuroLex |

| Olfactory sensation | Smell; the faculty of smell, the sensation that results when olfactory receptors in the nose are stimulated by particular chemicals in gaseous form. (NCI) * The sensation or perception of scents or odors. (MSH) * The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors. (GO:ai, http://www.onelook.com/) (GO) * sensation or perception of scents or odors; sense of smell.

| Olfactory Structures of CIVM postnatal rat brain atlas | The olfactory structures (olfactory bulbs, olfactory tubercles, and piriform cortex) can be segmented in coronal T2-weighted or diffusion-weighted images. Rostrally, the olfactory bulbs are free-floating and therefore easily segmented. Further caudal, as the isocortex appears dorsally, the border between the two is defined by the thin rostral extent of the lateral olfactory tract, which is dark on T2 MRI. A horizontal line connecting the two rhinal fissures that is slightly convex towards the dorsal surface of brain approximates the dividing line between these two regions of cortex as far caudal as the mamillary bodies. Caudal to the mamillary bodies the dividing line between isocortex and piriform cortex can be defined based on the dorsal extent of layer 2 of the piriform cortex, which appears quite dark (high diffusivity) of diffusion-weighted images. At roughly the caudal extent of the amygdala (the posteromedial cortical amygdaloid nucleus) the piriform cortex disappears abruptly giving way to the entorhinal cortex, which we have included in the isocortex. | ILX:0107969 | 3 | FDI Lab - SciCrunch.org | 06/18/2018 | FDI Lab - SciCrunch.org | term | 12/09/2016 | 0 | NeuroLex | NeuroLex |
| Olfactory sulcus | The medial orbital gyrus presents a well-marked antero-posterior sulcus, the olfactory sulcus, for the olfactory tract. [WP,unvetted]. | ILX:0107970 | 11 | FDI Lab - SciCrunch.org | 06/23/2020 | FDI Lab - SciCrunch.org | term | 12/09/2016 | 0 | NeuroLex | NeuroLex |
| Olfactory system | The sensory system used for olfaction, or the sense of smell. Most mammals and reptiles have two distinct parts to their olfactory system: a main olfactory system and an accessory olfactory system. The main olfactory system detects volatile, airborne substances, while the accessory olfactory system senses fluid-phase stimuli. Behavioral evidence indicates that most often, the stimuli detected by the accessory olfactory system are pheromones.The olfactory system is often spoken of along with the gustatory system as the chemosensory senses because both transduce chemical signals into perception. - definition adapted from Wikipedia | ILX:0107971 | 9 | FDI Lab - SciCrunch.org | 06/23/2020 | FDI Lab - SciCrunch.org | term | 12/09/2016 | 0 | NeuroLex | NeuroLex |
| Olfactory system function | The olfactory system in most vertebrate species consists of two distinct subsystems: the main olfactory system and the accessory olfactory system. The main olfactory system is generally considered to be important in the detection and processing of airborne chemicals whereas the accessory olfactory system is mainly used in the detection and processing of water-soluble chemicals (http://www.springerreference.com/docs/html/chapterdbid/332953.html). | ILX:0107972 | 3 | FDI Lab - SciCrunch.org | 06/18/2018 | FDI Lab - SciCrunch.org | term | 12/09/2016 | 0 | NeuroLex | NeuroLex |
| Olfactory trigone | A small triangular area in front of the anterior perforated substance. Its apex, directed forward, occupies the posterior part of the olfactory sulcus, and is brought into view by throwing back the olfactory tract (adapted from Wikipedia) | ILX:0107973 | 13 | FDI Lab - SciCrunch.org | 01/17/2023 | FDI Lab - SciCrunch.org | term | 12/09/2016 | 0 | NeuroLex | NeuroLex |
| Olfactory tubercle | Region in the ventral telencephalon, prominent in rodents, but present in all mammals, consisting of a laminated cortical part and the cap/hilus region. It is traditionally viewed as part of the olfactory cortex but recognized by some as having a striatal character. According to many authors, the structure of the OT transitions from cortical like to striatal like along the lateral medial axis.
