Processing of Odor Information During the Respiratory Cycle in Mice

open access: yesFrontiers 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.

Distraction of olfactory bulb-medial prefrontal cortex circuit may induce anxiety-like behavior in allergic rhinitis.

open access: yesPLoS ONE, 2019
Allergic rhinitis is a chronic inflammatory disease of the upper respiratory tract, which is associated with high incidence of anxiety symptom. There is evidence that medial prefrontal cortex modulates anxiety-related behaviors and receives projections ...

Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]

open access: yes, 1993
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.

Ion activities and potassium uptake mechanisms of glial cells in guinea-pig olfactory cortex slices. [PDF]

open access: yes, 1987
1. Double-barrelled ion-sensitive micro-electrodes were used to measure changes in the intracellular activities of K+, Na+ and Cl- (aiK, aiNa, aiCl) in glial cells of slices from guinea-pig olfactory cortex during repetitive stimulation of the lateral ...

The olfactory thalamus: unanswered questions about the role of the mediodorsal thalamic nucleus in olfaction

open access: yesFrontiers in Neural Circuits, 2015
The mediodorsal thalamic nucleus (MDT) is a higher order thalamic nucleus and its role in cognition is increasingly well established. Interestingly, components of the MDT also have a somewhat unique sensory function as they link primary olfactory cortex ...

Gain Control and Sparse Representations in the Olfactory System of the Locust and Fly [PDF]

open access: yes, 2010
The giant GABAergic neuron (GGN) is a single, paired, non-spiking neuron that arborizes extensively in the mushroom body (MB) of the locust (Leitch and Laurent, 1996), where it overlaps with the dendrites and the axons of Kenyon cells (KCs).

Neural Circuit Dynamics and Ensemble Coding in the Locust and Fruit Fly Olfactory System [PDF]

open access: yes, 2007
Raw sensory information is usually processed and reformatted by an organism’s brain to carry out tasks like identification, discrimination, tracking and storage.

Normal Olfactory Functional Connectivity Despite Lifelong Absence of Olfactory Experiences

open access: yes, 2021
Congenital blindness is associated with atypical morphology and functional connectivity within and from visual cortical regions; changes that are hypothesized to originate from a lifelong absence of visual input and could be regarded as a general (re ...

Topological reorganization of odor representations in the olfactory bulb. [PDF]

open access: yes, 2007
Odors are initially represented in the olfactory bulb (OB) by patterns of sensory input across the array of glomeruli. Although activated glomeruli are often widely distributed, glomeruli responding to stimuli sharing molecular features tend to be ...

Functional connectivity patterns in parosmia

open access: yesBehavioral and Brain Functions, 2023
Objective Parosmia is a qualitative olfactory dysfunction presenting as “distorted odor perception” in presence of an odor source. Aim of this study was to use resting state functional connectivity to gain more information on the alteration of olfactory ...
