The electromagnetic spectrum is the term used by scientists to describe the entire range of light that exists. From radio waves to gamma rays, most of the light in the universe is, in fact, invisible to us! Light is a wave of alternating electric and magnetic fields.The propagation of light isnât much different than waves crossing an ocean.nother closely related property is wavelength: the distance from the peak of one wave to the peak of the next. These two attributes are inversely related. The larger the frequency, the smaller the wavelength â and vice versa. You can remember the order of the colors in the visible spectrum with the mnemonic ROY G BV.
The lateralization of brain function refers to how some functions, or cognitive processes tend be more dominant in one hemisphere than the other. The medial longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.f a specific region of the brain, or even an entire hemisphere, is injured or destroyed, its functions can sometimes be assumed by a neighboring region in the same hemisphere or the corresponding region in the other hemisphere, depending upon the area damaged and the patient's age.
The term brain lateralization refers to the fact that the two halves of the human brain are not exactly alike. Each hemisphere has functional specializations: some function whose neural mechanisms are localized primarily in one half of the brain.In humans, the most obvious functional specialization is speech and language abilities.he bottom line is that, despite overly-simplistic descriptions of left-brain / right-brain stuff one finds in introductory textbooks and the public press, there is still a great deal about brain lateralization that we simply do not yet understand.
