memory_task_neuromod

An fMRI experiment on memory

Protocol

Images are randomly shown to subject in one of four quadrants on screen. Participants must memorize these images and their respective position. Later, are shown the same images along with novel ones and must remember if the image was seen earlier and if so, in which quadrant.
