A greenhouse gas is a gas that is transparent to visible light but opaque to infrared light. As sunlight enters the atmosphere it is short wave radiation. Greenhouse gases allow shortwave radiation to pass through them. When the sunlight hits the Earth it warms the Earth. As a result of this the warmed Earth emits heat or long wave radiation. Greenhouse gases are not transparent to energy of this wave length so they trap the heat. The reason they are called greenhouse gases is because they work like the windows of a greenhouse works, allowing the sunlight to enter but trapping the heat inside.

Midbrain. The midbrain, also called the mesencephalon, is a small region of the brain that serves as a relay center for visual, auditory, and motor system information. It regulates autonomic functions, those that the body carries out without conscious thought, such as digestion, heart rate, and breathing rate.
