For vertebrates, the early stages of neural development are similar across all species. As the embryo transforms from a round blob of cells into a wormlike structure, a narrow strip of ectoderm running along the midline of the back is induced to become the neural plate, the precursor of the nervous system. The neural plate folds inward to form the neural groove, and then the lips that line the groove merge to enclose the neural tube, a hollow cord of cells with a fluid-filled ventricle at the center. At the front end, the ventricles and cord swell to form three vesicles that are the precursors of the forebrain, midbrain, and hindbrain. At the next stage, the forebrain splits into two vesicles called the telencephalon (which will contain the cerebral cortex, basal ganglia, and related structures) and the diencephalon (which will contain the thalamus and hypothalamus). At about the same time, the hindbrain splits into the metencephalon (which will contain the cerebellum and pons) and the myelencephalon (which will contain the medulla oblongata). Each of these areas contains proliferative zones where neurons and glial cells are generated; the resulting cells then migrate, sometimes for long distances, to their final positions.
The vesicle that contains the cerebral cortex is which one?
telencephalon

A thriving market of unlicensed NES hardware clones emerged during the climax of the console's popularity. Initially, such clones were popular in markets where Nintendo never issued a legitimate version of the console. In particular, the Dendy (Russian: Де́нди), an unlicensed hardware clone produced in Taiwan and sold in the former Soviet Union, emerged as the most popular video game console of its time in that setting and it enjoyed a degree of fame roughly equivalent to that experienced by the NES/Famicom in North America and Japan. A Famicom clone was marketed in Argentina under the name of "Family Game", resembling the original hardware design. The Micro Genius (Simplified Chinese: 小天才) was marketed in Southeast Asia as an alternative to the Famicom; Samurai was the popular PAL alternative to the NES; and in Central Europe, especially Poland, the Pegasus was available. Samurai was also available in India in early 90s which was the first instance of console gaming in India.
What was the name of the clone in Poland?
Pegasus

Another significant issue unique to LaserDisc is one involving the inconsistency of playback quality between different makers and models of player. On most televisions, a given DVD player will produce a picture that is visually indistinguishable from other units. Differences in image quality between players only becomes easily apparent on large televisions and substantial leaps in image quality are generally only obtained with expensive, high-end players that allow for post-processing of the MPEG-2 stream during playback. In contrast, LaserDisc playback quality is highly dependent on hardware quality. Major variances in picture quality appear between different makers and models of LD players, even when tested on a low to mid-range television. The obvious benefits of using high quality equipment has helped keep demand for some players high, thus also keeping pricing for those units comparably high. In the 1990s, notable players sold for anywhere from US$200 to well over $1,000, while older and less desirable players could be purchased in working condition for as little as $25.
Is LaserDisc quality consistent or inconsistent between player brands?
inconsistency
