We, the Editors and Publishers of Neurological Research, are retracting the following articles:

Following an investigation by Wayne State University into the research conducted by Dr CW Kreipke, it has been determined to retract the above articles. The University found that several images presented in the above articles were also used to represent different results in grant proposals and/or poster presentations authored by Dr Kreipke. The University concluded that the data were fundamentally unreliable and recommended that the above articles should be retracted.
We have been informed in our decision-making by the guidance of COPE guidelines on retractions.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
