Participants can learn to regulate neural patterns in opposite directions using decoded neurofeedback (DecNef). However, subsequent training sessions show reduced effectiveness due to prior learning interference.
Area of Science:
- Neuroscience
- Cognitive Science
Background:
- Real-time functional magnetic resonance imaging (rt-fMRI) enables multi-voxel pattern decoding for neurofeedback.
- Decoded neurofeedback (DecNef) offers potential for manipulating fine-grained neural activity.
Purpose of the Study:
- To investigate if participants can learn bidirectional neural pattern induction using DecNef.
- To examine the impact of prior learning on subsequent DecNef effectiveness.
Main Methods:
- A within-subjects design with two counterbalanced DecNef training sessions for opposing behavioral changes (confidence regulation).
- Nonlinear mathematical modeling to analyze learning effects, directionality, maintenance, and interference.
Main Results:
- DecNef successfully induced bidirectional confidence changes within participants.
- Up-regulation effects were more prominent than down-regulation; changes were maintained for a week.
- Second training sessions showed diminished effectiveness, indicating strong anterograde learning interference.
Conclusions:
- DecNef can train opposing neural patterns within individuals.
- Anterograde learning interference significantly impacts subsequent DecNef sessions.
- Findings have implications for neuroscience, training, and therapeutic applications.
