Size, however, is not the only difference: there are also substantial differences in shape. The hindbrain and midbrain of mammals are generally similar to those of other vertebrates, but dramatic differences appear in the forebrain, which is greatly enlarged and also altered in structure. The cerebral cortex is the part of the brain that most strongly distinguishes mammals. In non-mammalian vertebrates, the surface of the cerebrum is lined with a comparatively simple three-layered structure called the pallium. In mammals, the pallium evolves into a complex six-layered structure called neocortex or isocortex. Several areas at the edge of the neocortex, including the hippocampus and amygdala, are also much more extensively developed in mammals than in other vertebrates.

The hippocampus and amygdala are ares inside what structure?
Answer: neocortex

According to Tony Sclafani from MSNBC, "It's worth noting that before Madonna, most music mega-stars were guy rockers; after her, almost all would be female singers ... When The Beatles hit America, they changed the paradigm of performer from solo act to band. Madonna changed it backwith an emphasis on the female." Howard Kramer, curatorial director of the Rock and Roll Hall of Fame and Museum, asserted that "Madonna and the career she carved out for herself made possible virtually every other female pop singer to follow ... She certainly raised the standards of all of them ... She redefined what the parameters were for female performers." According to Fouz-Hernandez, subsequent female singers such as Britney Spears, Christina Aguilera, Kylie Minogue, the Spice Girls, Destiny's Child, Jennifer Lopez, and Pink were like her "daughters in the very direct sense that they grew up listening to and admiring Madonna, and decided they wanted to be like her." Time magazine included her in the list of the "25 Most Powerful Women of the Past Century", where she became one of only two singers to be included, alongside Aretha Franklin. She also topped VH1's lists of "100 Greatest Women in Music" and "50 Greatest Women of the Video Era".

Who is the other woman who earned the title?
Answer: Aretha Franklin

In Mexico, Carnival is celebrated in about 225 cities and towns. The largest is in Mazatlan and the city of Veracruz with others in Baja California and Yucatan. The larger city Carnivals employ costumes, elected queens and parades with floats, but Carnival celebrations in smaller and rural areas vary widely depending on the level of European influence during Mexico's colonial period. The largest of these is in Huejotzingo, Puebla where most townspeople take part in mock combat with rifles shooting blanks, roughly based on the Battle of Puebla. Other important states with local traditions include Morelos, Oaxaca, Tlaxcala and Chiapas.

About how many cities and towns in Mexico is Carnival celebrated in?

225
