RESEARCH TOPICS
Choose a field to explore.
Start with the technology itself or explore one of the wider scientific areas connected with vagal and autonomic research.
Technology
Vagus Nerve Stimulation (VNS)
Research across implanted and non-invasive approaches, mechanisms, neuromodulation and brain–body pathways.
Transcutaneous Vagus Nerve Stimulation (tVNS)
Research on non-invasive vagus nerve stimulation delivered through the skin, including stimulation sites and protocol variables.
Transcutaneous Auricular Vagus Nerve Stimulation (taVNS)
Research on ear-based stimulation targeting the auricular branch of the vagus nerve.
Research areas
Safety & Tolerability
Human research examining adverse events, tolerability and safety reporting across taVNS studies.
Autonomic Regulation
Research on sympathetic and parasympathetic activity, recovery and the body's shift between physiological states.
Heart Rate Variability (HRV)
Research examining HRV as a marker of autonomic activity, including its uses and limitations.
Inflammation & Neuroimmune Signalling
Research on neural–immune communication, inflammatory signalling and the cholinergic anti-inflammatory pathway.
Gut–Brain Communication
Research on neural, hormonal, microbial and immune communication between the digestive system and the brain.
