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?
A: neocortex

Transport is one of the four main areas of policy administered by the Mayor of London, however the mayor's financial control does not extend to the longer distance rail network that enters London. In 2007 he assumed responsibility for some local lines, which now form the London Overground network, adding to the existing responsibility for the London Underground, trams and buses. The public transport network is administered by Transport for London (TfL) and is one of the most extensive in the world.
Along with the London Underground, buses and trans, what form of public rail transport was added in 2007 to the Mayor's responsibilities?
A:
the London Overground network
