脑干的研究传统上集中在控制肢体或轴向肌肉或维持体内平衡的机制（例如，用于调节呼吸或血压的电路）。然而，最近的研究表明，心肺活动的运动和变化往往是协调的，这表明控制躯体运动活动的途径与调节呼吸或循环的途径之间存在联系。在诸如孤束核和外侧延髓网状结构等调节循环和呼吸的区域中的神经元已被证明接收指示身体在空间中的位置的躯体感觉信号（包括来自前庭系统的那些）。此外，躯体运动控制可能会受到来自内脏感受器的信号的影响，这些内脏感受器提供了关于身体在空间中的位置的线索。脑干的某些区域也可能直接参与运动控制以及血压和呼吸的调节。因此，将脑干简单地划分为“躯体”和“自主”区域不再可能。
Studies of the brainstem have traditionally either focused on mechanisms for the control of limb or axial muscles or for the maintenance of homeostasis (e.g., the circuitry for the regulation of respiration or blood pressure). However, recent studies have demonstrated that movement and changes in cardiorespiratory activity often are coordinated, indicating a linkage between the pathways that control somatic motor activity and those that regulate respiration or circulation. Neurons in regions such as nucleus tractus solitarius and the lateral medullary reticular formation that regulate circulation and respiration have been shown to receive somatic sensory signals (including those from the vestibular system) indicating body position in space. In addition, somatic motor control may be influenced by signals from visceral receptors that provide cues regarding body position in space. Some areas of the brainstem may also participate directly in both motor control and regulation of blood pressure and respiration. Thus, a simple division of the brainstem into “somatic” and “autonomic” regions is no longer possible.
