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...
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).
17 sie 2022 · We discovered an extensive white matter network extending from the olfactory bulb to form novel connections directly to other cortices of the brain. This is the first documentation of these novel olfactory connections and provides new insight into how dogs integrate olfactory stimuli in their cognitive functioning.
19 lut 2022 · The shape of the nasal cavity is particularly distinctive in dogs. Numerous studies have established that dogs and their olfactory ability are of great importance in searching for lost people, detecting explosives or drugs as well as signaling disease in the human body.
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.
2 paź 2018 · Dogs may follow their nose, but they learn associations to many types of sensory stimuli. Are some modalities learned better than others?
1 lis 2021 · At a closer evaluation, this finding makes sense considering that the olfactory system in dogs is displayed ipsilaterally (which means affecting the same side of the body), and therefore, their right nostril connects with the right side of the brain, while their left nostril connects to the right.
