Volumetric vs Surface-Based Intersubject Alignment of Auditory Cortex Activation

This study explores the differences in volumetric and surface-based intersubject alignment techniques for localizing activation in the auditory cortex. We analyze phonemes and tones using flattened patches and landmarks corresponding to the atlas, while addressing deformations for individual patches. Our findings highlight the importance of methodology in ensuring accurate localization and comparison of auditory processing across subjects. This research, conducted by Rutvik Desai and colleagues at the Medical College of Wisconsin, enhances understanding of auditory cortex functions.
