19 lip 2022 · Powerful nerve connections link the dog nose to wide swaths of the brain, researchers report July 11 in the Journal of Neuroscience. One of these canine connections, a hefty link between...
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.
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).
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 ...
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.
24 lip 2016 · The development of the canine visual system is incomplete at birth, as evidenced by the sealed eyelids of a neonate. The palpebral reflexes are present at birth, but most of the other protective responses do not appear until later (Table 2-1). Even after the eyes open, development continues.
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.
