19 lip 2022 · July 19, 2022 at 9:00 am. A dog’s brain is wired for smell. Now, a new map shows just how extensive that wiring is. Powerful nerve connections link the dog nose to wide swaths of the...
26 sie 2022 · There are more than 300 million scent receptors in a dog’s snout, which is why dogs are used to sniff out drugs, bombs, firearms, and even diseases. Now newfound research shows there’s a more powerful connection between dogs’ noses and their brains than people originally thought.
21 sie 2021 · Here, we provide an overview of canine olfaction, discussing aspects connected with anatomy, physiology, behavioral aspects of sniffing, and factors influencing the olfactory abilities of the ...
1 lut 2024 · Dog nose is on the left, nasal cavity in the middle and the brain on the right. Odor molecules travel first through the nose and respiratory epithelium (yellow) towards the upper region of the nasal cavity where they are captured by olfactory receptor cells that are embedded within the olfactory mucosa in olfactory epithelium (green).
20 lip 2022 · In the dog brain, sturdy neural tracts run from the olfactory bulb (bottom left) to five distinct spots. A newfound connection (orange) links the olfactory system to vision, something that has so far been found only in dogs.
17 sie 2022 · In this study, we found extensive white matter connectivity from the olfactory bulb to the cerebral cortex of the canine brain using DTI MRI and Klingler dissection. Five white matter tracts were found across subjects—the OOT, OPT, OLT, OET, and OCST.
19 lut 2022 · This work aimed at summing up the state of knowledge on the shape of the nasal cavity and airflow in these domestic animals and dealt with the brachycephalic syndrome (BOAS) and anatomical changes in the initial airway area in dogs with a short and widened skull.
