• How many neurophysiologists -- does it take to change a light bulb?
  Six. One to remove the old bulb and examine it under the microscope to find out what went wrong, one to blow a tube of glass into the bulb shape, one to coil the tungsten wire filament, one to clean up the metal base of the old bulb, one to operate the vacuum pump to get rid of the air in the bulb and one to apply the glue to seal the new bulb into the old base....
