The role of the piriform cortex in temporal lobe epilepsy: A current literature review [PDF]
Frontiers in Neurology, 2022 Temporal lobe epilepsy is the most common form of focal epilepsy and can have various detrimental consequences within many neurologic domains. Recent evidence suggests that the piriform cortex may also be implicated in seizure physiology.

Occurrence of new neurons in the piriform cortex [PDF]
Frontiers in Neuroanatomy, 2015 Adult neurogenesis has been well studied in hippocampus and subventricular zone; while this is much less appreciated in other brain regions, including amygdala, hypothalamus and piriform cortex.

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.

Elevated tau in the piriform cortex in Alzheimer's but not Parkinson's disease using PET‐MR [PDF]
Alzheimer’s & Dementia: Diagnosis, Assessment & Disease MonitoringINTRODUCTION Olfactory dysfunction can be an early sign of Alzheimer's disease (AD). We used tau positron emission tomography‐magnetic resonance (PET‐MR) to analyze a key region of the olfactory circuit, the piriform cortex, in comparison to the adjacent

Interictal blood–brain barrier dysfunction in piriform cortex of people with epilepsy [PDF]
Annals of Clinical and Translational NeurologyObjective The piriform cortex is considered to be highly epileptogenic. Its resection during epilepsy surgery is a predictor for postoperative seizure freedom in temporal lobe epilepsy. Epilepsy is associated with a dysfunction of the blood–brain barrier.

LRP4 is required for the olfactory association task in the piriform cortex [PDF]
Cell & Bioscience, 2022 Background Low-density lipoprotein receptor-related protein 4 (LRP4) plays a critical role in the central nervous system (CNS), including hippocampal synaptic plasticity, maintenance of excitatory synaptic transmission, fear regulation, as well as long ...

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 ...

Lineage Relationships Between Subpallial Progenitors and Glial Cells in the Piriform Cortex [PDF]
Frontiers in Neuroscience, 2022 The piriform cortex is a paleocortical area, located in the ventrolateral surface of the rodent forebrain, receiving direct input from the olfactory bulb.

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

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 ...
