Immature olfactory sensory neurons provide behaviourally relevant sensory input to the olfactory bulb

Nature Communications, 2022
New olfactory sensory neurons (OSNs) wire into highly organized olfactory bulb circuits throughout life. Here, the authors show that immature OSNs provide behaviourally relevant sensory input to olfactory bulb neurons that is functionally distinct from ...

Glomerular microcircuits in the olfactory bulb [PDF]

Neural Networks, 2009
Microcircuits in the olfactory bulb have long received particular attention from both experimentalists and theoreticians, due in part to an abundance of dendrodendritic interactions and other specialized modifications to the canonical cortical circuit architecture.

An Integrated and Robust Deep Learning Framework for Denoising and Analyzing Single‐Cell Spatial Transcriptomics

Advanced Intelligent Systems, EarlyView.
Single‐cell Spatial Transcriptomics Analysis and Denoising Engine is introduced as a unified deep learning framework that jointly performs denoising, clustering, and gene prioritization in spatial transcriptomics. By integrating linear and nonlinear representations within a dual‐channel architecture, it improves robustness and accuracy, uncovers ...

Paced-mating increases the number of adult new born cells in the internal cellular (granular) layer of the accessory olfactory bulb. [PDF]

PLoS ONE, 2011
The continuous production and addition of new neurons during life in the olfactory bulb is well accepted and has been extensively studied in rodents. This process could allow the animals to adapt to a changing environment.

Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Scalp electroacupuncture targeting trigeminal nerve activation alleviates post‐traumatic stress disorder–induced depression and neuroinflammation in mice

Animal Models and Experimental Medicine, EarlyView.
Scalp electroacupuncture (SA) through activation of the trigeminal pathway exerts anti‐inflammatory, antidepressant, and anxiolytic effects in an animal model of post‐traumatic stress disorder induced by single prolonged stress. This suggests that SA is involved in neuroinflammation and changes in brain‐derived neurotrophic factor protein through the ...

Zebrafish Astroglial Morphology in the Olfactory Bulb Is Altered With Repetitive Peripheral Damage

Frontiers in Neuroanatomy, 2020
Zebrafish do not possess the typical astrocytes that are found in mammalian systems. In some brain areas, this teleost has radial glia that appears to perform astrocyte-like functions, but these cells have not been described in the zebrafish olfactory ...

Olfactory Neuroscience: Beyond the Bulb [PDF]

Current Biology, 2011
High-resolution tracing of projections from the olfactory bulb to its cortical targets revealed coarse topography and stereotopy in some areas but highly distributed, combinatorial connectivity in others. These results provide a basis for understanding innate and associative olfactory processing and perception.

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Photoperiod mediated changes in olfactory bulb neurogenesis and olfactory behavior in male white-footed mice (Peromyscus leucopus). [PDF]

PLoS ONE, 2012
Brain plasticity, in relation to new adult mammalian neurons generated in the subgranular zone of the hippocampus, has been well described. However, the functional outcome of new adult olfactory neurons born in the subventricular zone of the lateral ...
