Neurological Basis of Shaking in Wet Mammals

Scientists discover the neurological mechanism behind the shaking behavior of wet mammals, linking it to ultrasensitive receptors and potentially to tickling sensations.

What is the main finding of the study published in Science?
The study, published in Science, reveals that the shaking behavior in mammals like dogs is not random but a neurological reflex triggered by C-LTMR mechanoreceptors.
What is the primary function of the shaking behavior in animals?
The shaking action helps remove water, insects, or other irritants from the animal's fur, acting as a protective mechanism.
What other sensory response may be linked to this shaking mechanism?
There's a possible link between the shaking response and tickling sensations, as the same C-LTMR receptors may be involved in both, according to the study's lead author.
What specific type of receptors trigger the shaking response in mammals?
These C-LTMRs are ultrasensitive receptors that activate when something irritates the fur, sending signals to the brainstem to initiate the shaking response.
How did researchers confirm the role of these receptors in the shaking behavior?
The researchers used optogenetics and ablation techniques on mice to confirm the role of C-LTMRs in triggering the shaking behavior; eliminating them stopped the shaking.
