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).
12 lip 2023 · Dogs have complex, lateralized behaviors and wide variation in brain size, providing an ideal opportunity to assess relationships between brain size, behavioral lateralization, and brain asymmetries. Here, we performed complementary voxel-based and source-based morphometry analyses using MRI images from 62 dogs of 33 breeds.
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...
The canine olfactory bulb is 3 times larger in dogs than in humans, which may be related to their superior olfactory abilities. This structure receives information about smell directly from the nose, and helps discriminate between odors. Midbrain. Hidden within the brain is the midbrain.
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.
The central nervous system includes the spinal cord and the brain. The brain is divided into 3 main sections—the brain stem, which controls many basic life functions, the cerebrum, which is the center of conscious decision-making, and the cerebellum, which is involved in movement and motor control. The spinal cord of dogs is divided into ...
