Anterior olfactory nucleus mediates parallel inter-bulbar pathways in rodents

BMC Biology
Background Interhemispheric communication of olfactory information is crucial for accurate odor perception and odor source localization in animals. However, the underlying structural basis for this communication in mammals remains poorly understood ...

Histopathology of the olfactory pathway due to ischemia [PDF]

The Laryngoscope, 1984
AbstractVarious agents, such as trauma, viral infections and neoplasms cause olfactory dysfunction. However, little is understood concerning the role of ischemia. An experimental model of brain ischemia was developed in the Mongolian gerbil, and the olfactory pathway was studied.

Chemo- and Thermosensory Responsiveness of Grueneberg Ganglion Neurons Relies on Cyclic Guanosine Monophosphate Signaling Elements [PDF]

, 2011
Neurons of the Grueneberg ganglion (GG) in the anterior nasal region of mouse pups respond to cool temperatures and to a small set of odorants. While the thermosensory reactivity appears to be mediated by elements of a cyclic guanosine monophosphate ...

Functional Reciprocal Connections between Olfactory and Gustatory Pathways [PDF]

Chemical Senses, 2005
peptide (CGRP) at a dilution of 1:4000 and then incubated in ABC solution. The location of the camera field in the slice was also histologically reconstructed. Results Mapping studies of field potentials Electrical stimulation of layer II in the PC evoked a field potential with a latency of 35 ms in the central region of the EPN. A field potential with

Predicting Macrophage Spatial Localization from Single‐Cell Transcriptomes to Uncover Disease Mechanisms

Advanced Science, EarlyView.
This study presents a machine‐learning framework entitled MERLIN that infers the microanatomical localization of macrophages from single‐cell transcriptomic data in structured organs such as the kidney and brain. Applying this method to existing datasets from models of acute kidney injury and diabetic nephropathy uncovered spatially resolved insights ...

Identification of novel post-transcriptional features in olfactory receptor family mRNAs. [PDF]

, 2015
Olfactory receptor (Olfr) genes comprise the largest gene family in mice. Despite their importance in olfaction, how most Olfr mRNAs are regulated remains unexplored.

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

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

The sense of smell, its signalling pathways, and the dichotomy of cilia and microvilli in olfactory sensory cells

BMC Neuroscience, 2007
Smell is often regarded as an ancillary perception in primates, who seem so dominated by their sense of vision. In this paper, we will portray some aspects of the significance of olfaction to human life and speculate on what evolutionary factors ...
