Ampullae of Lorenzini are physically associated with and evolved from the mechanosensory lateral line organs of early vertebrates.Passive electroreception using ampullae is an ancestral trait in the vertebrates, meaning that it was present in their last common ancestor. [7]
The human brain and eyes process light into color, allowing us to take in various shades of the rainbow.Our furry friends, however, do not see quite like we do. When you're out for a stroll with ...
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.
At one end of each of the semicircular ducts is a dilated sac called a membranous ampulla, which is more than twice the diameter of the ducts. Each ampulla contains an ampullary crest, the crista ampullaris which consists of a thick gelatinous cap called a cupula and many hair cells. The superior and posterior semicircular ducts are oriented ...
Interblobs are areas between blobs that receive the same input, but are sensitive to orientation instead of color. They output to the pale and thick stripes of area V2. Blobs are on the koniocellular pathway. This pathway begins at the photoreceptors which then relay signals to the 'K' ganglion cells in the retina. The pathway then continues ...
The video showcases a scene that any dog lover would find irresistible: several dogs, exhausted from an hour of running hard at a local park, struggle to keep their eyes open during the ride back ...
The macula (/ˈmakjʊlə/) [1] or macula lutea is an oval-shaped pigmented area in the center of the retina of the human eye and in other animals. The macula in humans has a diameter of around 5.5 mm (0.22 in) and is subdivided into the umbo, foveola, foveal avascular zone, fovea, parafovea, and perifovea areas.
Beta brain waves, which are associated with attention and concentration, became stronger when participants played with Aro, brushed her or gave her a gentle massage — a sign that people's ...
