Illustrating the Day after Effect of Brain Activation

Caption

The brain image at the back presents spontaneous (resting state) patterns before a fMRI-based neurofeedback training session. The front brain image presents spontaneous (resting state) patterns a day after the training session, illustrating the long term trace of the training. The two brains are overlaid above scatter plots of individual subjects that demonstrate the "Hebbian-like" learning rule: Cortical sites that were co-activated during training increased their resting state connectivity, while those that were de-correlated during training decreased it. For more information, see the article by Harmelech et al. Journal of Neuroscience, 33(22):9488-97 2013.
