The dye used for echo is different from the dye used during angiography (a test used to examine the body's blood vessels). For most types of echo, you will remove your clothing from the waist up. Women will be given a gown to wear during the test. You'll lie on your back or left side on an exam table or stretcher.
In case youâre like me and canât get your head on straight about which is which, the left brain is the math/science/logical side and the right brain is the art/music/creative side. Obviously we tend to skew pretty far towards the right-brain around these parts, but we respect all types of brain power and have a special place in our hearts for science and chess.
When a 2004 study asked participants to think about a favorite food, resulting functional MRI images showed that three primary areas of the brain lit up: the hippocampus, insula and caudate. The hippocampus is in the temporal lobe and filters sensory data to store it in short-term or long-term memory. The insula, which is located on either side of the brain, helps to control your social emotions by interpreting what physical state you are in. The caudate nucleus, which is in the striatrum in the center of the brain, helps to control the body's dopamine reward system. Dopamine, a feel-good hormone, also is produced during gambling, sex and drug activity.
