Piriform cortex ictogenicity in vitro
Experimental Neurology, 2019The piriform cortex is recognized to play critical roles in focal ictogenesis, both in animal models and in humans. We review here the contribution of in vitro studies performed on rodent brain tissue that were aimed at understanding the ictogenic properties of the piriform cortex and the contiguous olfactory areas.

Kindling-induced potentiation in the piriform cortex
Brain Research, 1991At intensities sufficient to induce epileptiform afterdischarges, repeated electrical stimulation of limbic structures can lead to the development of permanent increases in the strength of the epileptiform response (kindling). Field potentials evoked by pulse stimulation are also increased in amplitude in a number of forebrain pathways following ...

Neurogenesis in the adult rat piriform cortex
NeuroReport, 2006Multipotent neural precursors have been suggested to exist in many parts of the adult mammalian brain. In the present study, we characterized the neurogenic potential in the piriform cortex of adult rats. Proliferation rates as detected by 5'-bromodeoxyuridine-labeling proved to be low when compared with the major neurogenic brain regions (i.e.

The primary olfactory cortex, or piriform cortex, has been the focus of considerable modeling research. These models range from early work focused on electroen-cephalographic (EEG) data to more recent work constructing networks from com-partmental biophysical simulations of individual neurons.

THE ROLE OF THE PIRIFORM CORTEX IN KINDLING
Progress in Neurobiology, 1996In epilepsy research, there is growing interest in the role of the piriform cortex (PC) in the development and maintenance of limbic kindling and other types of limbic epileptogenesis leading to complex partial seizures, i.e. the most common type of seizures in human epilepsy.

Optical recording of the rat piriform cortex activity
Progress in Neurobiology, 1997The piriform cortex (PCx) is a phylogenetically old brain structure which presents characteristics of a content-addressable memory. Taking into account its particular anatomo-functional organization, we hypothesized that this cortex could behave rather as an assembly of different functional units than as a functionally homogeneous structure.

Piriform cortex late activity revealed functional spatial heterogeneity
NeuroReport, 1995Optical signals were recorded in the in vivo rat piriform cortex (PC) in response to olfactory bulb electrical stimulation. Sometimes the early response was followed by a longer latency component with an occurrence probability of 0.25. In order to compare the early and late activity, the ratio between early (disynaptic) and late wave amplitudes was ...

Anatomical imaging of the piriform cortex in epilepsy
Experimental Neurology, 2019The piriform cortex is a distinct brain region that plays a key role in the sense of smell. The piriform cortex is the major part of primary olfactory cortex and has broad connections that extend beyond the olfactory regions into limbic and fronto-temporal cortical networks.

Acetylcholine and associative memory in the piriform cortex
Molecular Neurobiology, 1997The significance of cholinergic modulation for associative memory performance in the piriform cortex was examined in a study combining cellular neurophysiology in brain slices with realistic biophysical network simulations. Three different physiological effects of acetylcholine were identified at the single-cell level: suppression of neuronal ...

Piriform (Olfactory) cortex model on the hypercube
Proceedings of the third conference on Hypercube concurrent computers and applications -, 1988We present a concurrent hypercube implementation of a neurophysiological model for the piriform (olfactory) cortex.The project was undertaken as the first step towards constructing a general neural network simulator on the hypercube, suitable both for applied and biological nets.The method presented here is expected to be useful for a class of complex ...
