Patterns of Gray and White Matter Volume Alterations in Patients With Post-Traumatic Anosmia: A Voxel-Based Morphometry Study

Frontiers in Neurology, 2022
ObjectiveTraumatic brain injury is one of the major causes of human olfactory dysfunction and leads to brain structure alterations, mainly in the cortical olfactory regions.

Neurons and circuits for odor processing in the piriform cortex [PDF]

, 2013
Increased understanding of the early stages of olfaction has lead to a renewed interest in the higher brain regions responsible for forming unified ‘odor images’ from the chemical components detected by the nose.

Convulsant actions of 4-aminopyridine on the guinea-pig olfactory cortex slice [PDF]

, 1982
The effects of bath-applied 4-aminopyridine on neurones and extracellular potassium and calcium concentrations were recorded in slices of guinea-pig olfactory cortex. Neurones were orthodromically activated by stimulating the lateral olfactory tract.

Processing of Odor Information During the Respiratory Cycle in Mice

Frontiers in Neural Circuits, 2022
In the mouse olfactory system, odor signals detected in the olfactory epithelium are converted to a topographic map of activated glomeruli in the olfactory bulb.

Complementary Sensory and Associative Microcircuitry in Primary Olfactory Cortex [PDF]

, 2011
The three-layered primary olfactory (piriform) cortex is the largest component of the olfactory cortex. Sensory and intracortical inputs converge on principal cells in the anterior piriform cortex (aPC).Wecharacterize organization principles of the ...

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.

Effects of intranasal instillation of nanoparticulate matter in the olfactory bulb

Scientific Reports, 2021
Nanoparticulate matter activates the aryl hydrocarbon receptor (AhR) pathway in the respiratory system in a process involving the AhR nuclear translocator (ARNT) and cytochrome P450 family 1, member A1 (CYP1A1).

Chromogranin A in the olfactory system of the rat [PDF]

, 1990
The olfactory bulb of the rat contains chromogranin A at a similar level as the adrenal gland or the hypophysis as revealed by immunoblots. Olfactory chromogranin A also displays the same size as chromogranin A of endocrine cells.

Learning to smell danger: Acquired associative representation of threat in the olfactory cortex

Frontiers in Behavioral Neuroscience, 2014
Neuroscience research over the past few decades has reached a strong consensus that the amygdala plays a key role in emotion processing. However, many questions remain unanswered, especially concerning emotion perception.
