Post-traumatic olfactory loss and brain response beyond olfactory cortex [PDF]
Scientific Reports, 2021 Olfactory impairment after a traumatic impact to the head is associated with changes in olfactory cortex, including decreased gray matter density and decreased BOLD response to odors. Much less is known about the role of other cortical areas in olfactory

Olfactory-trigeminal integration in the primary olfactory cortex. [PDF]
Hum Brain Mapp, 2020 ABSTRACT Humans naturally integrate signals from the olfactory and intranasal trigeminal systems. A tight interplay has been demonstrated between these two systems, and yet the underlying neural circuitry that mediates olfactory-trigeminal integration remains poorly understood.

Olfactory consciousness and gamma oscillation couplings across the olfactory bulb, olfactory cortex and orbitofrontal cortex [PDF]
Frontiers in Psychology, 2013 The orbitofrontal cortex receives multi-modality sensory inputs, including olfactory input, and is thought to be involved in conscious perception of the olfactory image of objects.

Pyramidal Cells in Olfactory Cortex. [PDF]
Chem Senses, 2021 Abstract The neocortex and olfactory cortices share many features including their laminar organization, developmental sequences, and cell types. Previous work indicates that neocortical pyramidal cells exhibit a gradient of dendritic size: cells involved in the initial processing of information are less complex than those in subsequent ...

Sex differences in olfactory cortex neuronal loss in aging [PDF]
Frontiers in Human Neuroscience, 2023 IntroductionAging plays a major role in neurodegenerative disorders such as Alzheimer’s disease, and impacts neuronal loss. Olfactory dysfunction can be an early alteration heralding the presence of a neurodegenerative disorder in aging.

Acquisition of non-olfactory encoding improves odour discrimination in olfactory cortex. [PDF]
Nat Commun, 2023 Abstract Primary sensory cortices, initially considered elementary encoders of physicochemical attributes of environmental stimuli, are now known to be modulated by other aspects of experience, such as attentional state and internal expectations 1–3 , movement-related signals

A topographical organization in the primary olfactory cortex. [PDF]
Nat CommunA key principle of most sensory cortices is their topographic organization, in which neurons in proximity exhibit similar tuning properties, typically varying along a specific stimulus feature. However, such an organization has not yet been identified in the olfactory system.

Inhibition by Somatostatin Interneurons in Olfactory Cortex. [PDF]
Front Neural Circuits, 2016 Inhibitory circuitry plays an integral role in cortical network activity. The development of transgenic mouse lines targeting unique interneuron classes has significantly advanced our understanding of the functional roles of specific inhibitory circuits in neocortical sensory processing.

Optophysiological analysis of associational circuits in the olfactory cortex [PDF]
Frontiers in Neural Circuits, 2012 Primary olfactory cortical areas receive direct input from the olfactory bulb, but also have extensive associational connections that have been mainly studied with classical anatomical methods. Here, we shed light on the functional properties of associational connections in the anterior and posterior piriform cortices (aPC and pPC) using ...
