Stereotaxic Coordinates of Human Hypothalamic Nuclei Used for Region of Interest Analyses in Functional Magnetic Resonance Imaging.

Abstract

The hypothalamus maintains homeostasis by controlling various organs and the central nervous system, but analyzing the human hypothalamic nuclei is challenging. Our previous studies applied areal parcellation to high-resolution functional magnetic resonance imaging (fMRI) data to delineate hypothalamic nuclei boundaries. This article presents stereotaxic coordinates of these nuclei for fMRI analyses, offering guidance on defining regions of interest and appropriate spatial smoothing kernel sizes. The provided coordinates aid future research in nuclear level hypothalamus analyses.
