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.

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 ...

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.

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.

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.

Quantification of Amyloid and Tau associations in the Piriform Cortex in Alzheimer's and Parkinson's Disease using PET‐MR [PDF]

Alzheimers Dement
Abstract Background Olfactory‐associated regions, particularly the piriform cortex, may harbor early pathological changes in Alzheimer's (AD) and Parkinson's disease (PD). Amyloid–tau overlap is strongest in the medial temporal lobe. Amyloid–tau association in the piriform cortex versus other medial temporal structures remains unclear. We used dual PET‐

Neural mechanisms of economic choices in mice [PDF]

, 2020
Economic choices entail computing and comparing subjective values. Evidence from primates indicates that this behavior relies on the orbitofrontal cortex. Conversely, previous work in rodents provided conflicting results. Here we present a mouse model of

The Wire Is Not the Territory: Understanding Representational Drift in Olfaction With Dynamical Systems Theory

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.
