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 · Advances in the non-invasive brain imaging of domestic dogs offer one way for better understanding the mechanisms behind the dog’s olfactory abilities as well as cognitive and emotional processing of scents.
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? We used awake fMRI in 19 dogs over a series of three...
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.
18 lip 2022 · Cornell researchers have provided the first documentation that dogs’ sense of smell is integrated with their vision and other unique parts of the brain, shedding new light on how dogs experience and navigate the world.
Humans also have an olfactory bulb, but it is much smaller and is hidden underneath the frontal lobe. 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
