Watch out for crosstalk!

Nature Communications study sheds light on risk to data quality in brain recordings

Prof. Dr. Thomas Stieglitz, Chair of Biomedical Microtechnology and co-spokesperson of the BrainLinks BrainTools Center, and his co-authors have published a new study on risks to data analysis in brain recordings. Especially with the advancing miniaturization of neurotechnological implants, false-positive results can arise due to unwanted electrical crosstalk between adjacent channels. With the help of a model, the researchers have succeeded in eliminating these errors and ensuring valid data evaluation.

The work emphasizes the critical importance of data quality control in the recording of brain activity. It also suggests that potential sources of error should be considered when designing neural interfaces in order to minimize the risk of crosstalk.
