The Piriform Cortex and Human Focal Epilepsy [PDF]
Frontiers in Neurology, 2014 It is surprising that the piriform cortex, when compared to the hippocampus, has been given relatively little significance in human epilepsy. Like the hippocampus, it has a phylogenetically preserved three-layered cortex that is vulnerable to excitotoxic

Intracranial investigation of piriform cortex epilepsy during odor presentation. [PDF]
Neurocase, 2023 Abstract The piriform cortex is part of the olfactory system, principally receiving input from the lateral olfactory tract and projecting to downstream components of the olfactory network, including the amygdala. Based on preclinical studies, the piriform cortex is vulnerable to injury and can be easily kindled as an onset site for seizures ...

Mixture Coding and Segmentation in the Anterior Piriform Cortex [PDF]
Frontiers in Systems Neuroscience, 2020 Coding of odorous stimuli has been mostly studied using single isolated stimuli. However, a single sniff of air in a natural environment is likely to introduce airborne chemicals emitted by multiple objects into the nose.

Essential Role of the Anterior Piriform Cortex in Mediating Social Novelty Output via a Top–Down Circuit [PDF]
Advanced ScienceSocial novelty is indispensable for a wide range of social behaviors. The medial prefrontal cortex (mPFC), along with other social information hubs, composes the foundational circuitry of social novelty.

Differential connectivity of the posterior piriform cortex in Parkinson’s disease and postviral olfactory dysfunction: an fMRI study [PDF]
Scientific ReportsOlfactory dysfunction is a common feature of both postviral upper respiratory tract infections (PV) and idiopathic Parkinson’s disease (PD). Our aim was to investigate potential differences in the connectivity of the posterior piriform cortex, a major ...

Lateral entorhinal cortex afferents reconfigure the activity in piriform cortex circuits. [PDF]
Proc Natl Acad Sci U S AAbstractOdours are key signals for guiding spatial behaviours such as foraging and navigation in rodents. It has recently been found that odour representations in the piriform cortex (PCx) can also contain information about their spatial context. However, the precise origins of this information within the brain and its subsequent integration into the ...
