Oscillatory Sequences of Firing in the Locust Olfactory System: Mechanisms and Functional Significance [PDF]

open access: yes, 1999
What neural codes does the brain use to represent and process sensory information? Stimulus-evoked oscillatory synchronization of neuronal activity has been observed in many systems, yet the possible functions of such rhythmic synchronization in neural ...

A study of neural activity and functional connectivity within the olfactory brain network in Parkinson's disease

open access: yesNeuroImage: Clinical, 2019
Olfactory dysfunction is an early manifestation of Parkinson's disease (PD). The present study aimed to illustrate potential differences between PD patients and healthy controls in terms of neural activity and functional connectivity within the olfactory

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

open access: yesFrontiers 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.

Preprocessing of emotional visual information in the human piriform cortex

open access: yesScientific 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.

Alterations of Cerebral Blood Flow and Its Connectivity in Olfactory-Related Brain Regions of Type 2 Diabetes Mellitus Patients

open access: yesFrontiers in Neuroscience, 2022
To investigate the alteration of cerebral blood flow (CBF) and its connectivity patterns in olfactory-related regions of type 2 diabetes mellitus (T2DM) patients using arterial spin labeling (ASL).

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]

open access: yes, 2006
Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

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

open access: yesFrontiers 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.

Effects of intranasal instillation of nanoparticulate matter in the olfactory bulb

open access: yesScientific 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).

Chemosensory Convergence on Primary Olfactory Cortex [PDF]

open access: yesThe Journal of Neuroscience, 2012
Food perception and preference formation relies on the ability to combine information from both the taste and olfactory systems. Accordingly, psychophysical investigations in humans and behavioral work in animals has shown that the taste system plays an integral role in odor processing.

Chemosensory Learning in the Cortex

open access: yesFrontiers in Systems Neuroscience, 2011
Taste is a primary reinforcer. Olfactory-taste and visual-taste association learning takes place in the primate including human orbitofrontal cortex to build representations of flavour.
