3-D Brain Cartography Obtained from the Conventional Electroencephalogram on Paper.The electroencephalogram (EEG) is the most used clinical test for assessing brain function. It is a non-invasive technique which provides a rapid detection of brain dysfunction. Nowadays, diagnosisbased on the EEG curves is widely used, but its correct interpretation requires a lot of training and knowledge. On the other hand, brain cartography is an important complement of the EEG. It represents the EGG curves as a 2D or 3D color map, over the head’s surface, which sinthetizes the electric information captured by the electrodes at a given time. There are very sophisticated digital EEG devices that generate a 3D cartrography of the brain. However, such devices are very expensive. In addition, most medical centers in developing countries have conventional EGGdevices with chart paper output. This work presents the development of a software application which generates 3D maps of the brain’s electrical activity from the conventionalelectroencephalogram on paper. In this way, an ancient and conventional analogic EGG becomes a modern digital EGG at a very low cost.
