Historically neurosurgeons were taken to be better dealing with minute details, i.e., using microscope / loupes for surgery like decompression and discectomies and spine surgeons (orthopedics) in bony work like fusions and deformity correction.
This behavior relates to Charles Law of Gases (Gay-Lussac's Law also applies in terms of pressure changes in a rigid container). You may have noticed that car tires and balloons shrink in cold weather. This is due to the molecular motion of gas particles. The gas particles slow down as temperature decreases. This, in turn, decreases their force exerted on the container walls and surrounding particles. The reverse is also true if temperature is increased. Youtube has a 90 minute TV special that relates temperature and absolute zero to the behavior of matter.
If the pressure of a gas is held constant, its volume is proportional to the temperature. As the temperature increases, the atoms move faster and require more space so that they strike the walls of the container with the same net force. The volume increases. If the temperature of a gas is held constant, its pressure is inversely proportional to the volume. If the volume of a gas is decreased, then the same number of atoms moving at the same speed (because the temperature has not changed) will strike the walls of the container more often.
