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.
Meteorologists use a variety of tools to help them gather information about weather and climate. Some more familiar ones are thermometers which measure air temperature, anemometers which gauge wind speeds, and barometers which provide information on air pressure.
