About

The proposed research applies the highly innovative technology of real-time functional Magnetic Resonance Imaging (rtfMRI) to examine plasticity of brain-regulatory mechanisms related to cognitive and affective processing and to determine benefits for cognition and affect in young and older adults and in Parkinson Disease (PD) patients.

Full description

There is increasing evidence that age-related alterations in brain function associated with affective processing and attention contribute to these motivational and emotional changes with age.

Based on these theoretical considerations as well as the previous study's data, the proposed research will apply well-tested emotion processing and attention paradigms to address the pivotal question of whether brain activity can be modulated in healthy aging and PD (in the substudy) via contingent rt-fMRI neurofeedback and whether this neuroregulatory modulation increases emotion processing and cognitive performance.
