But the speed of a wave has nothing to do with the amplitude of its crests and troughs. Speed is measured by the distance the wave travels in a certain amount of time. Specifically, it's measured in meters per second.We already have the 'per second' part down. wave is a disturbance that travels through a medium in a periodic fashion, carrying energy without transporting matter. Waves are described and measured by five wave parameters: the period, the frequency, the amplitude, the wavelength, and the speed.
The biggest part of the brain is the cerebrum. It makes up about 85 % of the brain's weight. Its surface has a lot of wrinkles and cracks. The cerebrum is the thinking part of the brain. It controls your muscles and makes them move when you want them to.When you think hard, try to solve a math problem or draw a picture you use your cerebrum. It is also the area which stores your memory. The cerebrum has two halves.he cerebellum is a lot smaller than the cerebrum and sits at the back of the brain. It's very important because it controls balance, movement and the way your muscles work together. It allows you to stand on your feet without falling down or lets you balance your weight on a surfâ or snowboard.
Brain Area for Decision-Making and Planning is âUniquely Humanâ. Star Trek may have told us that space is humanityâs final frontier, but plenty of uncharted hinterland remains unexplored within the human brain. And scientists at Oxford University recently discovered an area of the brain that contributes to make humans, well, human. The walnut-sized area, nestled within the frontal cortex, is called the lateral frontal pole. Itâs responsible for planning and decision-making and, according to the new findings, has no equivalent in the monkey brain. Researchers thus believe this brain region might be responsible for humansâ upper hand in tasks that require strategic planning, decision-making and multitasking. Exploring the Brain The researchers compared MRI images of humansâ and macaquesâ ventrolateral frontal cortex, a region of the brain that controls language and complex thought processes.
