Volumetric analysis of the piriform cortex in temporal lobe epilepsy [PDF]
Epilepsy Research, 2022 The piriform cortex, at the confluence of the temporal and frontal lobes, generates seizures in response to chemical convulsants and electrical stimulation.

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

Representations of Odor in the Piriform Cortex [PDF]
Neuron, 2009 Olfactory perception is initiated by the recognition of odorants by a large repertoire of receptors in the sensory epithelium. A dispersed pattern of neural activity in the nose is converted into a segregated map in the olfactory bulb. How is this representation transformed at the next processing center for olfactory information, the piriform cortex ...

Rhythmic Spontaneous Activity in the Piriform Cortex [PDF]
Cerebral Cortex, 2007 Slow spontaneous rhythmic activity is generated and propagates in neocortical slices when bathed in an artificial cerebrospinal fluid with ionic concentrations similar to the ones in vivo. This activity is extraordinarily similar to the activation of the cortex in physiological conditions (e.g., slow-wave sleep), thus representing a unique in vitro ...

Convergence in the Piriform Cortex [PDF]
Neuron, 2011 How are the responses to distinct chemical features integrated to form an olfactory perceptual object? In this issue of Neuron, Davison and Ehlers show that individual piriform cortex neurons receive convergent input from up to 10% of main olfactory bulb glomeruli and are activated by specific spatial patterns of coactive glomeruli.

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.

Neurons and circuits for odor processing in the piriform cortex [PDF]
Trends in Neurosciences, 2013 Increased understanding of the early stages of olfaction has lead to a renewed interest in the higher brain regions responsible for forming unified 'odor images' from the chemical components detected by the nose. The piriform cortex, which is one of the first cortical destinations of olfactory information in mammals, is a primitive paleocortex that is ...

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.

INHIBITORY INTERNEURONS IN THE PIRIFORM CORTEX
Clinical and Experimental Pharmacology and Physiology, 2007 SUMMARY The piriform cortex (PC) is the largest subdivision of the olfactory cortex and the first cortical destination of olfactory information. Despite the relatively simple anatomy of the PC and its obvious appeal as a model system for the study of cortical sensory processing, there are many outstanding questions about its basic cell physiology.

Binaral Interactions in the Rat Piriform Cortex [PDF]
Journal of Neurophysiology, 1997 Wilson, Donald A. Binaral interactions in the rat piriform cortex. J. Neurophysiol. 78: 160–169, 1997. Single-unit recordings were made from layer II/III anterior piriform cortex (aPCX) neurons in adult Wistar rats to examine odor response patterns to unilaterally and bilaterally delivered stimuli.
