These fibres signal the size of the detected electric field to the fish's brain. [14] The ampulla contains large conductance calcium-activated potassium channels (BK channels). Sharks are much more sensitive to electric fields than electroreceptive freshwater fish, and indeed than any other animal, with a threshold of sensitivity as low as 5 nV/cm.
Granulomatous meningoencephalitis (GME) is an inflammatory disease of the central nervous system (CNS) of dogs and, rarely, cats.It is a form of meningoencephalitis.GME is likely second only to encephalitis caused by canine distemper virus as the most common cause of inflammatory disease of the canine CNS.

First signs of this immune dysregulation can show through lethargy and the reluctance to walk. Behavioral changes and an abnormal mentation might occur. [6] After a short amount of time vestibulo-cerebellar symptoms will rapidly progress, leaving the animal in a state of depressed consciousness having seizures, amaurosis and ataxia.
Skin conditions in dogs are very common, so it's important to recognize the symptoms and understand the factors that cause them. Dr. Rebecca MacMillan, a vet with over 15 years of experience, says ...
The cupula is the onion-shaped structure surrounded by endolymph in the ampulla. The ampullary cupula, or cupula, is a structure in the vestibular system, providing the sense of spatial orientation. The cupula is located within the ampullae of each of the three semicircular canals.
Interacting with dogs in such ways may strengthen people’s brain waves associated with rest and relaxation, as measured by brain tests, according to a small study published Wednesday in the ...
2. Hollow Food Puzzles. As the name implies, these food puzzles are hollow, as they are meant to be filled with food. Their shape makes it challenging for dogs to extract the food, keeping them ...
A dog's olfactory epithelium is also considerably more densely innervated, with a hundred times more receptors per square centimeter. [ 13 ] Molecules of odorants passing through the superior nasal concha of the nasal passages dissolve in the mucus that lines the superior portion of the cavity and are detected by olfactory receptors on the ...
