When the pulse finishes, the particles the release of the absorbed energy as they return for the alignment with the magnetic force. This set free energy is the measure of magnetic resonance signal. The constant information of these signals then are converted through computer software into an image of one slice of the brain. The resultant image is different of a photograph or a ray-x, is a representation of contrasts between the different ones weaveeed on the basis of the density of prtons of hydrogen and of the nature of the fabric I contend prtons (Detre and Wang 2002; Gore 2003; Heuttel, Song, and McCarthy 2004, Kandel, Schwartz, 2000 and Jessell; Patz 2007). During an experiment FMRI, investigators had made sweepings of the brain, while the individual is does not exert the interest function, related as a rest brain. After that, they play a destined experiment to activate the specific cerebral functions of interest, repeated many times to catch changes in the signal during the activity. The researchers adjust to the data of a myriad of factors, including the time delay between the neuronal activity and the arrival of the sanguine suppliment for the area, the cardiac movements of the head, beatings and breath. As a fingerprint, each brain is only, therefore, in studies involving more than a person, the researchers had discovered true ' ' teia' ' in each image of the brain of each participant of the brain for a model, in order that the cerebral localizations can be compared between the individuals.

One software program tests if in specific localities of the brain they are activated during the experiment. The program of colorful images of a brain in rest, it has in some places of significant increase in the sanguine flow, detaching the nets of neurons. Neuroimagem Persuasion The Researchers had investigated the nature of the process of decision and persuasion.
