Microscopically, there are differences between the neurons and tissue of the central nervous system and the peripheral nervous system. The central nervous system is divided in white and gray matter. This can also be seen macroscopically on brain tissue. The white matter consists of axons and oligodendrocytes, while the gray matter consists of neurons and unmyelinated fibers. Both tissues include a number of glial cells (although the white matter contains more), which are often referred to as supporting cells of the central nervous system. Different forms of glial cells have different functions, some acting almost as scaffolding for neuroblasts to climb during neurogenesis such as bergmann glia, while others such as microglia are a specialized form of macrophage, involved in the immune system of the brain as well as the clearance of various metabolites from the brain tissue. Astrocytes may be involved with both clearance of metabolites as well as transport of fuel and various beneficial substances to neurons from the capillaries of the brain. Upon CNS injury astrocytes will proliferate, causing gliosis, a form of neuronal scar tissue, lacking in functional neurons.

The Act also created the Gas Guzzler Tax which applies to the sales of vehicles with official EPA-estimated gas mileage below certain specified levels. In 1980, the tax was $200 for a fuel efficiency of 14 to 15 miles per gallon, and was increased to $1800 in 1985. In 1980, the tax was $550 for fuel efficiencies of 13 mpg and below, and was changed in 1986 to $3,850 for ratings below 12.5 mpg. The Gas Guzzler Tax only applies to passenger cars. Trucks, sport utility vehicles (SUV), and minivans are not covered because these vehicle types were not widely available in 1978 and were rarely used for non-commercial purposes. The tax is collected by the Internal Revenue Service (IRS) and normally paid by the manufacturer or importer. The following chart shows the tax for various levels of MPG as of 2006.

Firearms legislation in Switzerland allows the free purchase of semi-automatic, but not fully automatic firearms by Swiss citizens and foreigners with permanent residence. Permits for concealed carrying in public are issued sparingly. The acquisition of fully automatic weapons, silencers and target lasers likewise requires special permits issued by the cantonal firearms office. Use of hollow-point and soft-point ammunition is limited to hunting.
