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

Frontiers in Computational Neuroscience, 2015 Noradrenergic modulation from the locus coerulus is often associated with the regulation of sensory signal-to-noise ratio. In the olfactory system, noradrenergic modulation affects both bulbar and cortical processing, and has been show to modulate the ...

Tractography indicates lateralized differences between trigeminal and olfactory pathways
NeuroImage, 2022 Odorous sensations are based on trigeminal and olfactory perceptions. Both trigeminal and olfactory stimuli generate overlapping as well as distinctive activations in the olfactory cortex including the piriform cortex.

Chronic loss of inhibition in piriform cortex following brief, daily optogenetic stimulation
Cell Reports, 2021 SUMMARY It is well established that seizures beget seizures, yet the cellular processes that underlie progressive epileptogenesis remain unclear. Here, we use optogenetics to briefly activate targeted populations of mouse piriform cortex (PCx) principal ...

Cerebral Cortex Expression of Gli3 Is Required for Normal Development of the Lateral Olfactory Tract. [PDF]
PLoS ONE, 2015 Formation of the lateral olfactory tract (LOT) and innervation of the piriform cortex represent fundamental steps to allow the transmission of olfactory information to the cerebral cortex.

Developmental Dynamics of Piriform Cortex [PDF]
Cerebral Cortex, 2010 The piriform cortex (PCX) is a trilaminar paleocortex that is of interest for its role in odor coding and as a model for studying general principles of cortical sensory processing. While the structure of the mature PCX has been well characterized, its development is poorly understood.

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.

Topics in Cognitive Science, EarlyView., 2023 Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Fast and slow feedforward inhibitory circuits for cortical odor processing
eLife, 2022 Feedforward inhibitory circuits are key contributors to the complex interplay between excitation and inhibition in the brain. Little is known about the function of feedforward inhibition in the primary olfactory (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 ...
