The Arizona Sonora border was established as a result of the Gadsden Purchase of 1853. It runs through desert and mountain country, from the western Chihuahuan Desert by New Mexico through a zone of grassland and oak-covered hills to the classic Sonoran Desert west of Nogales. The land gets more and more arid as one travels west, and the western third of the border is essentially devoid of human habitation. It is this stretch of the border, once a major road to the Colorado River, that has earned and kept the title El Camino del Diablo, "The Devil's Highway."</span>

It was abandoned next year, but other settlements on Hispaniola took over (and they were earlier than the other options).

Behavioral
neuroscientists use non-invasive brain imaging techniques for various uses such
as: detecting brain impairments or abnormalities, studying brain anatomy and investigating
which areas of the brain show most activity when performing particular tasks or
activities. Some non-invasive brain imaging techniques include fMRI, MRI and
EEG.
