Sham lesion is the name given to a control procedure during a lesion experiment. In a sham lesion, an animal may be placed in a stereotaxic apparatus and electrodes inserted as in the experimental condition, but no current is passed, and therefore damage to the tissue should be minimal.
Meteorologists often work eight to 12-hour rotating shifts so that they can cover any meteorological event. The quintessential 9 to 5 work schedule is not common for meteorologists unless they are working in an administrative position, or at a facility with limited hours.
Meteorology is the science of atmospheric phenomena -- in particular, the weather. Math, physics and chemistry form the basis of meteorological knowledge. The very broad roles of meteorologists range from studying how pollution affects the climate to warning people of approaching danger.
