The Rhomboid Nucleus (Rh) is a midline thalamic nucleus located in the dorsal third ventricle, adjacent to the paratenial and paraventricular nuclei. It forms part of the dorsal thalamic midline and is involved in integrating visceral, emotional, and arousal-related information. The Rhomboid Nucleus receives input from the hypothalamus, brainstem, and limbic structures, and projects to cortical and subcortical targets involved in emotion and memory.
