Original sentence: Currently, Just and colleagues are conducting research on "thought recognition" using fMRI.During test trials, the system compares the neural activation patterns to those produced during the learning phase and chooses the object which produced an activation pattern compatible with the one produced during the test phase.Just and colleagues are in the process of expanding upon this research to increase its accuracy and scope.The system performs this task by displaying images of objects to participants in the learning phase, and subsequently displaying two images in the test phase.They have developed a system that is capable of recognizing the neural activation signatures associated with certain objects
Edited sentence: 4CAPS model have been used to explain behavioral and brain imaging data in different experimental tasks.A demo of their system was shown on CBS during 60 Minutes.Marcel Just also developed 4CAPS, a cognitive architecture specifies how different cortical regions of the brain collaborate to perform specific tasks.Marcel Just, Tom Mitchell and colleagues at Carnegie Mellon University are conducting research on "thought recognition" using fMRI.These signature patterns could be generalized across different participants, so that the authors were able to correctly identify which object a participant was thinking of by analyzing the corresponding brain activation.Using machine learning techniques, they have been able to identify patters of brain activation that are reliably associated to the concept of different objects
