In the 1960s, Vallbo and Hagbarth established the microneurography technique in which nerve impulses are recorded directly from a peripheral nerve from conscious humans in realtime (Vallbo, 2018). Microneurography has since had a tremendous impact on the field of integrative neurophysiology, enabling a wide array of studies interrogating the function of sensory afferent nerves, and efferent sympathetic nerves directed to muscle (MSNA) and skin (SSNA). In particular, microneurography of sympathetic nerves has advanced our understanding of the neural control of the circulation in both healthy and diseased populations. It has been used to examine sympathetic nervous system (SNS) regulation by control mechanisms such as baroreflexes, SNS reactivity to stress, the exercise pressor reflex, mechanisms underlying SNS overactivation in chronic disease, prognostic value of MSNA, and sex and race differences in SNS regulation to name a few examples. Importantly, microneurography has added valuable information to clinical trials testing the impact of targeted pharmacologic and nonpharmacologic interventions on SNS function in patient populations.In the current issue of J Physiol (Ottaviani et al., 2020), Ottaviani and colleagues report a case series of the first intraneural recordings from the cervical vagus nerve in humans using the microneurography technique. While microneurography has previously been used to record from various peripheral nerves including the peroneal, ulnar and median nerves, the vagus nerve had never previously been targeted, likely because of its close proximity to the internal carotid artery and internal jugular vein. The current study demonstrates that microelectrode penetration of the cervical vagus nerve can be safely and feasibly performed under ultrasound guidance, using a posterior approach that enables access to the vagus nerve without traversing the internal jugular vein.
