Intracortical Excitation Rules in Piriform Cortex [PDF]
, 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.

Preprocessing of emotional visual information in the human piriform cortex
Scientific Reports, 2017 This study examines the processing of visual information by the olfactory system in humans. Recent data point to the processing of visual stimuli by the piriform cortex, a region mainly known as part of the primary olfactory cortex.

Modulation of Inhibitory Synaptic Potentials in the Piriform Cortex [PDF]
Journal of Neurophysiology, 1999 Modulation of inhibitory synaptic potentials in the piriform cortex. Intracellular recordings from pyramidal neurons in brain slice preparations of the piriform cortex were used to test results from a computational model about the effects of cholinergic agonists on inhibitory synaptic potentials induced by stimulation of afferent fibers in layer Ia ...

Differential connectivity of the posterior piriform cortex in Parkinson’s disease and postviral olfactory dysfunction: an fMRI study [PDF]
Scientific ReportsOlfactory dysfunction is a common feature of both postviral upper respiratory tract infections (PV) and idiopathic Parkinson’s disease (PD). Our aim was to investigate potential differences in the connectivity of the posterior piriform cortex, a major ...

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.

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.

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.

Top-down feedback enables flexible coding strategies in the olfactory cortex
Cell Reports, 2022 Summary: In chemical sensation, multiple models have been proposed to explain how odors are represented in the olfactory cortex. One hypothesis is that the combinatorial identity of active neurons within sniff-related time windows is critical, whereas ...
