As part of the autonomic nervous system, the vagus nerve helps maintain homeostasis (or autonomic balance) by optimizing sympathetic (fight or flight) and parasympathetic (rest and digest) activities. It promotes relaxation, digestion, and other essential bodily functions during periods of rest and r...
diaphragm, lungs, throat, inner ear, and facial muscles. Practices that stimulate or relax these areas of the body can influence the tone of your vagus nerve. It is the body’s majorparasympatheticnerve responsible for basic functions, like the gag reflex, slowing the heart rate,...
IV. “Gut bacteriaimprove brain function by affecting the vagus nerve. Omega-3 fatty acids increase vagal tone and vagal activity. Studies shown that they reduce heart rate and increase heart rate variability, which means they likely stimulate the vagus nerve. And, high fish consumption is also ...
The development of vagus nerve stimulation (VNS) as a device-based therapy has accelerated the demand for a greater understanding of the vagal afferents and how they contribute to central nervous system (CNS) functions. The cervical vagus nerve where stimulation devices are commonly implanted contains...
Neuromodulation achieved by vagus nerve stimulation (VNS) induces various neuropsychiatric effects whose underlying mechanisms of action remain poorly understood. Innervation of neuromodulators and a microcircuit structure in the cerebral cortex informed
The anti-epileptic effects of vagus nerve stimulation (VNS) are associated with the thalamus, insular cortex, and other brain regions. OBJECTIVE: To validate the inhibitory effects of vagus nerve stimulation on firing activities of parafascicular nucleus (Pf) neurons in rats. DESIGN, TIME, AND ...
In safe environments, the vagus nerve suppresses primitive defense reflexes of the sympathetic system, favoring more efficient and soothing functions, known as the “social-engagement system” [20]. This activation leads to enhanced situational judgment, flexible behaviors, and pro-social traits, ...
Since there are no significant differences in EMG activities and c-Fos expression levels between male and female mice, our study mainly focused on male mice unless otherwise stated. Fig. 1: Identification of the stomach-vagus-NTS neural pathway. A Schematic representation of GD and c-Fos ...
though the nerve cells in the limb are fine, there's no longer a connection between them and the brain. Established rehab methods bypass the brain's damaged area and enlist other brain cells to handle the lost functions. However, there aren't many neurons to spare, so the patient has a...
Transcutaneous auricular vagus nerve stimulation (taVNS) shows excellent effects on relieving clinical symptoms in migraine patients. Nevertheless, the neurological mechanisms of taVNS for migraineurs remain unclear. In recent years, voxel-wise degree ce
