Scientists have recently carried out tests on volunteers to find out which areas in the brain are involved in face recognition． The tests must have been a lot of fun to take part in! The volunteers were_______a photograph of a famous person on a computer and then the face gradually changed into another famous person's． For example a picture of the 1950s film star Marilyn Monroe_______changed into a picture of the British Prime Minister Margaret Thatcher! Obviously， Marilyn's beautiful curly blonde hair became greyer， her nos became sharper and longer， and her face developed wrinkles and lines around the mouth． As they watched the person change， complicated equipment scanned thevlunteers' brains to see which parts of the brain were lighting up．

The_______showed that we use three main areas of the brain to identify people's faces． While one section of the brain looks at the physical features such as size and shape of eyes， another part identifies the face as known or unknown．_______， a third part of the brain is checking out the name or other information about the face in our memory． It sounds_______but it seems that human beings can store as many as 10，000faces in their memories and most of us can recognize about ninety per cent of our classmates up to thirty five years after we last saw them!
