The Olfactory System of Zebrafish as a Model for the Study of Neurotoxicity and Injury: Implications for Neuroplasticity and Disease

International Journal of Molecular Sciences, 2019
The olfactory system, composed of the olfactory organs and the olfactory bulb, allows organisms to interact with their environment and through the detection of odor signals.

Origin of wiring specificity in an olfactory map revealed by neuron type–specific, time-lapse imaging of dendrite targeting

eLife, 2023
How does wiring specificity of neural maps emerge during development? Formation of the adult Drosophila olfactory glomerular map begins with the patterning of projection neuron (PN) dendrites at the early pupal stage.

Regulatory mechanisms in olfactory system assembly and function [PDF]

, 2012
The mammalian sense of smell relies on the detection of odorants by a large family of G protein coupled receptors, encoded by ~1300 different genes in mice (Buck and Axel, 1991; Zhang et al., 2007).

Functional integration of “undead” neurons in the olfactory system

Science Advances, 2019
Undead neurons may underlie the evolution of new olfactory circuits. Programmed cell death (PCD) is widespread during neurodevelopment, eliminating the surpluses of neuronal production.

An update on anatomy and function of the teleost olfactory system

PeerJ, 2019
About half of all extant vertebrates are teleost fishes. Although our knowledge about anatomy and function of their olfactory systems still lags behind that of mammals, recent advances in cellular and molecular biology have provided us with a wealth of ...

Short-term memory trace mediated by termination kinetics of olfactory receptor. [PDF]

, 2016
Odorants activate receptors in the peripheral olfactory neurons, which sends information to higher brain centers where behavioral valence is determined.

Haploinsufficiency of autism causative gene Tbr1 impairs olfactory discrimination and neuronal activation of the olfactory system in mice

Molecular Autism, 2019
BackgroundAutism spectrum disorders (ASD) exhibit two clusters of core symptoms, i.e., social and communication impairment, and repetitive behaviors and sensory abnormalities.

The olfactory pathway in the peracarid crustacean Parhyale hawaiensis (Malacostraca): new insights into the evolution of olfactory processing in Pancrustacea

Open Biology
Our current understanding of the functional morphology of olfactory systems in arthropods largely relies on information obtained in hexapods. Existing analyses of the olfactory pathway in crustacean representatives have suggested that these animals share
