Turning negative into positives! Exploiting ‘negative’ results in Brain–Machine Interface (BMI) research

Results that do not confirm expectations are generally referred to as ‘negative’ results. While essential for scientific progress, they are too rarely reported in the literature – Brain–Machine Interface (BMI) research is no exception. This led us to organize a workshop on BMI negative results during the 2018 International BCI meeting. The outcomes of this workshop are reported herein. First, we demonstrate why (valid) negative results are useful, and even necessary for BMIs. These results can be used to confirm or disprove current BMI knowledge, or to refine current theories. Second, we provide concrete examples of such useful negative results, including the limits in BMI-control for complete locked-in users and predictors of motor imagery BMI performances. Finally, we suggest levers to promote the diffusion of (valid) BMI negative results, e.g. promoting hypothesis-driven research using valid statistical tools, organizing special issues dedicated to BMI negative results, or convincing institutions and editors that negative results are valuable

The role of agency in neurofeedback performance

International audienceNeurofeedback (NF) aims to elicit voluntary modulation of neural activity by providing online feedback (FB). In Motor Imagery (MI) NF, participants reduce sensorimotor activity by imagining movements. Providing FB improves modulation relative to simple MI. Yet, a lot of NF participants fail to learn to modulate targeted activity. Most studies feature abstract FB obscuring the causal link between the MI task and the FB. This may reduce the sense of agency, which is rooted in the consistency between predicted and actual sensory outcomes. FB transparency could increase this consistency, yielding better sense of agency and in turn better NF performance. In this study, we tested this hypothesis in a MI-NF EEG-based protocol with different FB conditions
