Measuring the olfactory bulb input-output transformation reveals a contribution to the perception of odorant concentration invariance

open access: yesNature Communications, 2017
Humans and other animals can recognize an odorant as the same over a range of odorant concentrations. It remains unclear whether the olfactory bulb, the brain structure that mediates the first stage of olfactory information processing, participates in ...

A subtype-specific critical period for neurogenesis in the postnatal development of mouse olfactory glomeruli. [PDF]

open access: yesPLoS ONE, 2012
Sensory input is essential for the normal development of sensory centers in the brain, such as the somatosensory, visual, auditory, and olfactory systems.

Metastasizing esthesioneuroblastoma in a dog [PDF]

open access: yes, 2014
A 7-year-old Afghan hound presented with a history of disorientation, loss of vision, and seizures. Magnetic resonance imaging helped identify a mass at the level of the main olfactory bulb that compressed and displaced adjacent tissues in the cribriform

A ventral glomerular deficit in Parkinson’s disease revealed by whole olfactory bulb reconstruction

open access: yesBrain : a journal of neurology, 2017
Olfactory dysfunction is common in Parkinson’s disease. Zapiec et al. devise a rigorous quantitative approach to describe the glomerular component of the entire human olfactory bulb.

Layer- and cell type-selective co-transmission by a basal forebrain cholinergic projection to the olfactory bulb

open access: yesNature Communications, 2017
Cholinergic neurons in the basal forebrain project heavily to the main olfactory bulb, the first processing station in the olfactory pathway. The projections innervate multiple layers of the main olfactory bulb and strongly influence odor discrimination,

Hyperhomocysteinemia induces injury in olfactory bulb neurons by downregulating Hes1 and Hes5 expression

open access: yesNeural Regeneration Research, 2018
Hyperhomocysteinemia has been shown to be associated with neurodegenerative diseases; however, lesions or histological changes and mechanisms underlying homocysteine-induced injury in olfactory bulb neurons remain unclear.

Metal concentrations and distributions in the human olfactory bulb in Parkinson’s disease

open access: yesScientific Reports, 2017
In Parkinson’s disease (PD), the olfactory bulb is typically the first region in the body to accumulate alpha-synuclein aggregates. This pathology is linked to decreased olfactory ability, which becomes apparent before any motor symptoms occur, and may ...

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

open access: yesMolecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

The Origin, Development and Molecular Diversity of Rodent Olfactory Bulb Glutamatergic Neurons Distinguished by Expression of Transcription Factor NeuroD1. [PDF]

open access: yesPLoS ONE, 2015
Production of olfactory bulb neurons occurs continuously in the rodent brain. Little is known, however, about cellular diversity in the glutamatergic neuron subpopulation.

Odor-Induced Neuronal Rhythms in the Olfactory Bulb Are Profoundly Modified in ob/ob Obese Mice [PDF]

open access: yes, 2017
Leptin, the product of the Ob(Lep) gene, is a peptide hormone that plays a major role in maintaining the balance between food intake and energy expenditure. In the brain, leptin receptors are expressed by hypothalamic cells but also in the olfactory bulb,
