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.

Odor identity can be extracted from the reciprocal connectivity between olfactory bulb and piriform cortex in humans

NeuroImage, 2021
Neuronal oscillations route external and internal information across brain regions. In the olfactory system, the two central nodes—the olfactory bulb (OB) and the piriform cortex (PC)—communicate with each other via neural oscillations to shape the ...

PSA Depletion Induces the Differentiation of Immature Neurons in the Piriform Cortex of Adult Mice

International Journal of Molecular Sciences, 2021
Immature neurons are maintained in cortical regions of the adult mammalian brain. In rodents, many of these immature neurons can be identified in the piriform cortex based on their high expression of early neuronal markers, such as doublecortin (DCX) and

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.

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.

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.

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

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 ...
