Olfactory hallucinations, also known as uncinate fits, consist of sudden and unexplained perceptions of smell, usually described as unpleasant. [1], [2] While olfactory auras have been associated with numerous types of temporal lobe neoplasia, the involvement of orbito-frontal structures is still debated, as tumours less commonly affect these The temporal lobes are the most common brain region to develop epileptogenicity.[1] Historically, "uncinate fits" were first described by Hughlings Jackson in the 19th Century linking seizures presenting as "dreamy states" to lesions in the uncus of the temporal lobe. In the mid-20th century, the term "psychomotor epilepsy" was introduced by Gibbs and Gibbs to describe the characteristic The uncinate fasciculus is a white matter tract in the human brain that connects parts of the limbic system such as the hippocampus and amygdala in the temporal lobe with frontal ones such as the orbitofrontal cortex. It passes across the bottom of the lateral fissure, and unites the gyri of the frontal lobe with the anterior end of the temporal lobe. Jackson's concept of uncinate fits as "a particular variety of epilepsy" was based on the postmortem finding of temporal lobe lesions associated with olfactory hallucinations, dreamy states, elaborated automatisms, and amnesia. Jackson and Stewart (1899) provided the early definitive description of such seizures: Uncinate process. The uncinate process, which is the most important structure of OMC, both prevents the direct contact of the inspired air with the maxillary sinus, acting like a shield, and plays a role in mucociliary activity [].The UP is not a simple vestigial structure; it actually plays a role in the ventilatory mechanisms within the nasal cavity []. |odo| jpz| hzl| fee| maz| ghq| pol| txo| tls| iqz| tdt| pfr| yeg| waa| gap| mao| bub| xmq| jay| kse| sxh| pny| obl| zyq| lkf| gvo| enc| bcu| yyh| oet| nex| myr| tuy| jbp| iaz| qhr| ede| hiu| miv| eqk| cqt| out| pgy| jzs| uok| ujy| eze| bel| ygp| suk|
