Real-time fMRI-based self-regulation of brain activation across different visual feedback presentations

Real-time fMRI-based self-regulation of brain activation across different visual feedback... AbstractThe current study is a first exploration of real-time self-regulation of functional magnetic resonance imaging (fMRI) activation based on several different visual neurofeedback presentations. Six healthy participants were engaged in self-regulation of regional fMRI activation in the posterior parietal cortex (PPC), by performing a mental calculation task. In different MR sessions, feedback was presented in the form of either a thermometer display (in vertical orientation), a circle display (increasing or decreasing in physical size), or a numbers display (Arabic digits). While self-regulation levels did differ between individuals, all six participants were able to significantly up-regulate their PPC activation with all three neurofeedback presentations. In addition to a successful general up-regulation, five out of six participants were furthermore capable of gradual self-regulation to multiple intensity levels. Taken together, the current study is a proof-of-concept demonstration of the feasibility of using multiple visual feedback presentations during gradual self-regulation of regional fMRI activation. Implications for future neurofeedback research and applications are discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Brain-Computer Interfaces Taylor & Francis
