The commissural nucleus of the arcuate (CAN), also known as the arcuate commissural nucleus, is located in the medial hypothalamus adjacent to the third ventricle. It plays crucial roles in neuroendocrine control, autonomic regulation, and metabolic homeostasis. The CAN is distinguished from the adjacent arcuate nucleus by its distinctive commissural connections and unique neuronal populations. [1]
The CAN is situated in the medial basal hypothalamus: [2]
Key connections: [3]
The CAN is centrally involved in stress integration: [4]
The CAN integrates multiple metabolic signals: [5]
The commissural nucleus of the arcuate was first described in detail by Swaab and colleagues in the 1970s. Early studies focused on its neuroendocrine functions, particularly CRH production. Subsequent research has elaborated its roles in stress, metabolism, and autonomic control. The CAN's distinctive commissural connections distinguish it from the adjacent arcuate nucleus and suggest unique functions in interhemispheric hypothalamic integration. [6]
