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.

Neurogenesis dynamics in the olfactory bulb: deciphering circuitry organization, function, and adaptive plasticity [PDF]
Neural Regeneration ResearchAdult neurogenesis persists after birth in the subventricular zone, with new neurons migrating to the granule cell layer and glomerular layers of the olfactory bulb, where they integrate into existing circuitry as inhibitory interneurons.

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

Influence of age on nicotinic cholinergic regulation of blood flow in rat’s olfactory bulb and neocortex [PDF]
Journal of Physiological SciencesThe olfactory bulb receives cholinergic basal forebrain inputs as does the neocortex. With a focus on nicotinic acetylcholine receptors (nAChRs), this review article provides an overview and discussion of the following findings: (1) the nAChRs-mediated ...

Olfactory bulb anomalies in KBG syndrome mouse model and patients [PDF]
BMC MedicineANKRD11 (ankyrin repeat domain 11) is a chromatin regulator and the only gene associated with KBG syndrome, a rare neurodevelopmental disorder. We have previously shown that Ankrd11 regulates murine embryonic cortical neurogenesis.

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 491-501, December 2022., 2022 Flight and freezing are two vital defensive behaviors in the process of avoiding natural enemies in mice. We investigated the neural activity in dPAG nuclei of mice under two defensive behaviors, and found different coding features between flight and freezing behaviors. Abstract Background Flight and freezing are two vital defensive behaviors that mice

Journal of Comparative Neurology, Volume 531, Issue 2, Page 314-335, February 2023., 2023 The main objective of this work was to obtain detailed information on the distribution and localization of the spexin (Spx) system in the sea bass brain. To this purpose, we first identified and characterized the spx1 gene and analyzed its expression in the central nervous system (CNS) of the European sea bass by using quantitative Real‐Time Polymerase

Structure and evolution of neuronal wiring receptors and ligands
Developmental Dynamics, Volume 252, Issue 1, Page 27-60, January 2023., 2023 Abstract One of the fundamental properties of a neuronal circuit is the map of its connections. The cellular and developmental processes that allow for the growth of axons and dendrites, selection of synaptic targets, and formation of functional synapses use neuronal surface receptors and their interactions with other surface receptors, secreted ...

Wiring the senses: Factors that regulate peripheral axon pathfinding in sensory systems
Developmental Dynamics, Volume 252, Issue 1, Page 81-103, January 2023., 2023 Abstract Sensory neurons of the head are the ones that transmit the information about the external world to our brain for its processing. Axons from cranial sensory neurons sense different chemoattractant and chemorepulsive molecules during the journey and in the target tissue to establish the precise innervation with brain neurons and/or receptor ...

Olfactory neurogenesis and its role in fear memory modulation
Frontiers in Behavioral Neuroscience, 2023 Olfaction is a critical sense that allows animals to navigate and understand their environment. In mammals, the critical brain structure to receive and process olfactory information is the olfactory bulb, a structure characterized by a laminated pattern ...
