Massive normalization of olfactory bulb output in mice with a 'monoclonal nose' [PDF]

eLife, 2016
Perturbations in neural circuits can provide mechanistic understanding of the neural correlates of behavior. In M71 transgenic mice with a “monoclonal nose”, glomerular input patterns in the olfactory bulb are massively perturbed and olfactory behaviors ...

Subpopulations of Projection Neurons in the Olfactory Bulb

Frontiers in Neural Circuits, 2020
Generation of neuronal diversity is a biological strategy widely used in the brain to process complex information. The olfactory bulb is the first relay station of olfactory information in the vertebrate central nervous system.

Quantitative analysis of healthy olfactory sulcus depth, olfactory tract length and olfactory bulb volume in the paediatric population: a magnetic resonance study

Folia Morphologica, 2021
BACKGROUND: The aim of this study was to determine the normal reference values for olfactory sulcus depth, olfactory tract length and olfactory bulb volume in the paediatric population with routine magnetic resonance imaging (MRI) and determine the ...

Microplastics in the Olfactory Bulb of the Human Brain.

JAMA Netw Open
Key Points Question Can microplastics reach the olfactory bulb in the human brain? Findings This case series analyzed the olfactory bulbs of 15 deceased individuals via micro-Fourier transform infrared spectroscopy and detected the presence of ...

Neuroanatomical Reflections of Childhood Obesity: Volumetric Analysis of the Pituitary Gland and Olfactory Bulb [PDF]

Children
Introduction: Obesity is a rapidly increasing condition that leads to serious health issues. The sense of smell, one of the oldest senses related to energy metabolism, has been increasingly studied in relation to obesity.

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

PLoS 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 ...

Neuronal pattern separation in the olfactory bulb improves odor discrimination learning

Nature Neuroscience, 2015
Neuronal pattern separation is thought to enable the brain to disambiguate sensory stimuli with overlapping features, thereby extracting valuable information.

High-fat diet triggers transcriptomic changes in the olfactory bulb [PDF]

Heliyon
Metabolic imbalance contributes to cognitive impairment, anxiety, depressive behavior, and impaired olfactory perception. Recent studies have focused on olfactory dysfunction in patients with obesity and diabetes accompanied by cognitive dysfunction ...

Independent control of gamma and theta activity by distinct interneuron networks in the olfactory bulb

Nature Neuroscience, 2014
Circuits in the brain possess the ability to orchestrate activities on different timescales, but the manner in which distinct circuits interact to sculpt diverse rhythms remains unresolved. The olfactory bulb is a classic example of a place in which slow

Neuronal organization of olfactory bulb circuits

Frontiers in Neural Circuits, 2014
Olfactory sensory neurons extend their axons solely to the olfactory bulb, which is dedicated to odor information processing. The olfactory bulb is divided into multiple layers, with different types of neurons found in each of the layers.
