Fissure filling is a treatment that improves the apparent clarity of a gemstone by removing air and replacing it with a substance that has a refractive index similar to the host material. Many different substances may be used to fill fissures: oils, resins, waxes, glass, and various polymers, to name a few.
Cerebral autoregulation is a process in mammals, which aims to maintain adequate and stable cerebral blood flow.hile most systems of the body show some degree of autoregulation, the brain is very sensitive to over-and underperfusion. Cerebral autoregulation plays an important role in maintaining an appropriate blood flow to that region.
Wrinkled cortex increases the surface area of the brain, thereby increasing the number of neurons. This makes human brain to be more efficient than other vertebrates. Cerebrum is longitudinally divided into two major hemispheres, namely, left hemisphere and right hemisphere by the cerebral fissure.The two hemispheres are connected by the corpus callosum, which is made up of nerve fibers.rinkled cortex increases the surface area of the brain, thereby increasing the number of neurons.
