ACPC

ACPC is an acronym that can refer to multiple terms across different fields. In neuroscience and medical imaging, ACPC most commonly denotes the anterior commissure–posterior commissure line, an anatomical reference used to orient and register brain images. The line connects the anterior commissure and posterior commissure and provides a consistent axis for aligning scans. This reference is used in stereotaxic procedures and in preprocessing pipelines to bring individual brains into a common coordinate space, enabling cross-subject comparisons and the application of standardized templates.

Beyond imaging, ACPC may stand for various organizations, projects, or concepts depending on the context. Because acronyms can have multiple meanings, identifying the intended sense requires attention to subject matter, field, and accompanying terminology. In scholarly and clinical texts, ACPC is typically clarified at first use to avoid ambiguity.

In summary, ACPC most often refers to the anterior commissure–posterior commissure line in brain imaging, serving as a key reference for spatial normalization and cross-subject analyses. When encountered in other domains, its meaning should be inferred from the surrounding context.
