Abstract: In this technical report we identify and report a problem with the process of volume to surface mapping that has potentially impacted studies that focus upon local neighborhood connectivity. We show that neighborhood correlations vary spatially with anatomical patterns (gyral structure) even when the underlying volumetric data is uncorrelated noise. We explore the effects of this anomaly across varying data resolutions and surface mesh densities. We finally propose an approach to mitigate these unwanted effects.
