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 ...

Doublecortin-immunoreactive neurons in the piriform cortex are sensitive to the long lasting effects of early life stress [PDF]
Frontiers in NeuroscienceThe olfactory system is a niche of continuous structural plasticity, holding postnatal proliferative neurogenesis in the olfactory bulbs and a population of immature neurons in the piriform cortex.

Spatial maps in piriform cortex during olfactory navigation [PDF]
Nature, 2020 SummaryOdors are a fundamental part of the sensory environment used by animals to inform behaviors such as foraging and navigation1, 2. Primary olfactory (piriform) cortex is thought to be dedicated to encoding odor identity3–8. Here, using neural ensemble recordings in freely moving rats performing a novel odor-cued spatial choice task, we show that ...

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.

Intracortical Excitation Rules in Piriform Cortex
, 2016 The cerebral cortex continuously encodes new sensory information and organizes it within an experiential intracortical framework. The cortical integration of internal and external information forms the associations that are the basis for higher order sensory representation, and ultimately, perception.
