BrainGym – Estimulación del nervio vago para generar relagación con TENS.

Stimulation of the auricular branch and cymba conchae.

TENS stimulation of the auricular branch of the vagus nerve that passes through the left ear.

Stimulation of the the vagus nerve through gentle electrical stimulation, improving vagus tone over time, to help users achieve more restful sleep, less stress, and better mood.

Vagus nerve stimulation (VNS). The vagus nerve is a major component of the autonomic nervous system, has an important role in the regulation of metabolic homeostasis, and plays a key role in the neuroendocrine-immune axis to maintain homeostasis through its afferent and efferent pathways. Vagus nerve stimulation (VNS) refers to any technique that stimulates the vagus nerve, including manual or electrical stimulation.


Pulse width: 200 milliseconds

Mode: Normal mode

Pulse frequency: 30 Hz (Unless directed to do a rotating frequency)

Intensity: To start, turn the dial up until you barely feel a sensation, then turn it down until you just barely don’t feel it. Leave it there. This is a “subthreshold” intensity.

Duration: Begin with 12 minutes per day, two-three times per day. This could be paired just prior or post meals. Or, try morning and evening. If the tVNS is too activating, avoid evenings and only use in the morning or mid- day. Work up to 15-17 minute sessions.

The Vagus Nerve Stimulation Accessory Kit is 1 part of the full kit.

The Treatment is proven treatment that is aimed at rebalancing your immune system and slowing the effects of aging for those over 55. The Ear piece (accessory kit) is used with the Tens Machine to target your autonomic nervous system that begins to dominate as we age. The autonomic nervous system creates an imbalance in your body and reduces optimal body functions, which can make us far more susceptible to illness as we become older.

The use of this product alongside the tens machine can improve age related imbalances. The use of the Vagus Nerve stimulator regulates and improves your:

  • Sleep
  • Digestion
  • Mood
  • Depression
  • Heart Rate

and your overall well being.

The stimulator is also well known to improve your mental health and help those who suffer from epilepsy.

Research done by major HNS hospitals shows a significant reduction in cluster headaches and migraines.

NERVANA is a wearable product that sends a gentle electrical wave through the left ear canal to stimulate the body’s Vagus nerve, while syncing with music. This elicits a calm, relaxed feeling for most users in a natural way, which stimulates the brain’s pleasure center, known to release neurotransmitters (the body’s feel-good messengers). In more technical terms….A central signal-processing circuit receives both music and stimulation signals and routes those signals appropriately to the two ear buds. The right ear bud receives only the right channel of the music signal. The proprietary left ear bud, in comparison, not only receives the left channel of the music signal at its speaker, it also receives the stimulation signal within the ear bud material itself, to deliver electrical stimulation to the inside surface of the ear canal and, thereby, the Vagus nerve.

Cranial electrotherapy stimulation (CES):

Cranial electrotherapy stimulation (CES) is a neuromodulation tool used for treating several clinical disorders, including insomnia, anxiety, and depression. More recently, a limited number of studies have examined CES for altering affect, physiology, and behavior in healthy, non-clinical samples. The physiological, neurochemical, and metabolic mechanisms underlying CES effects are currently unknown. Computational modeling suggests that electrical current administered with CES at the earlobes can reach cortical and subcortical regions at very low intensities associated with subthreshold neuromodulatory effects, and studies using electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) show some effects on alpha band EEG activity, and modulation of the default mode network during CES administration. One theory suggests that CES modulates brain stem (e.g., medulla), limbic (e.g., thalamus, amygdala), and cortical (e.g., prefrontal cortex) regions and increases relative parasympathetic to sympathetic drive in the autonomic nervous system. There is no direct evidence supporting this theory, but one of its assumptions is that CES may induce its effects by stimulating afferent projections of the vagus nerve, which provides parasympathetic signals to the cardiorespiratory and digestive systems.

Promising New Therapy for Autism: Transcutaneous Vagus Nerve Stimulation.

Researchers at Harvard Medical School recently published an article in the journal Frontiers in Neuroscience. The article is titled, “Transcutaneous Vagus Nerve Stimulation: A Promising Method for treatment of Autism Spectrum Disorders.”

What is transcutaneous vagus nerve stimulation (tVNS)?

Also called «Cranial Electrotherapy Stimulation (CES),» this is a technique where an electrical current is applied to the vagus nerve – a nerve that runs between the brain and many areas of the body, including the heart, gastrointestinal tract, and skin. The vagus nerve has important physical and emotional effects in the body and helps the body to achieve a balance between states of stress (“fight or flight”) and states of relaxation (“rest and digest”). Electrical stimulation of the vagus nerve can be done either through an implanted device or through an external device applied to the skin. Vagus nerve stimulation is an FDA-approved treatment for seizures. Research studies also support vagus nerve stimulation as a treatment for depression.

Can tVNS help in Autism?

In several research studies, children with autism who were treated with tVNS showed improvement in cognitive function, behavior, and seizure frequency. The authors of this article summarize the research evidence that suggests tVNS is a safe and promising treatment for Autism. Give us a call to learn more about tVNS therapy at Cortica.

Transcutaneous forms of VNS

The outer ear is supplied by three sensory nerves: the auriculotemporal nerve, the great auricular nerve, and the auricular branch of the vagus nerve (ABVN) []. The external auditory meatus and concha (cymba conchae and cavum conchae) of the ear are supplied mainly by the ABVN, and the cymba conchae is supplied exclusively by the ABVN. A transcutaneous method of VNS (t-VNS) targets the cutaneous receptive field of the ABVN. Applying an electrical stimulus to the left cymba conchae (using a stimulus intensity above the sensory detection threshold, but below the pain threshold) results in a brain activation pattern not dissimilar to that of left cervical VNS []. The use of t-VNS for treating epilepsy was first proposed in 2000 []. A t-VNS device (NEMOS; Cerbomed GmbH; Erlangen, Germany) received European clearance for the treatment of epilepsy and depression in 2010 and for the treatment of pain in 2012. These approvals were based primarily on preclinical studies of t-VNS as well as extrapolating the findings from preclinical and human studies of left cervical VNS.

Transcutaneous Electrical Nerve Stimulator (TENS) devices can also be employed to administer t-VNS, by situating contact electrodes in the region of the cymba conchae. Patients can self-administer t-VNS, which can be applied unilaterally or bilaterally (depending on the device system used), but there is no established clinical paradigm for how t-VNS should be administered (i.e., stimulation parameters; duration and frequency of each stimulation session; length of treatment; etc.). The NEMOS manufacturer suggests that each session should last at least one hour and should be used 3-4 times per day, but the basis for this recommendation is unclear. There is some published clinical data (mostly pilot studies) on the use of t-VNS for epilepsy, depression, pain, and other clinical indications, suggesting that it is safe and well tolerated [].

Another type of t-VNS device (gammaCore; electroCore LLC; Basking Ridge, NJ, USA) has European clearance for the prophylactic and acute treatment of cluster headache, migraine, hemicrania continua, and medication overuse headache. Therapy using gammaCore is delivered through a hand-held portable device with two flat stimulation contact surfaces that transmits a proprietary electrical signal in the vicinity of the vagus nerve. The device is placed on the neck over the vagus nerve, at a location where the pulse is found. The stimulation intensity is controlled by the patient and the application stimulation lasts for 90 seconds. Patients may experience headache relief when used as needed, but the device can be used several times per day to prevent headaches. Pilot studies and case series reports using the gammaCore device for primary headache syndromes have been described in abstract form and larger controlled trials are underway [], but this device has not been investigated in epilepsy or depression.

How To Stimulate the Vagus Nerve using a TENS Unit on Your Ear

VNS Therapy® (short for vagus nerve stimulation therapy) is a neuromodulation treatment designed for people with drug-resistant epilepsy 4 years of age and older with partial onset seizures. It can safely lead to fewer and shorter seizures and better recovery after seizures.

Non-invasive Vagus Nerve Stimulation in Healthy Humans Reduces Sympathetic Nerve Activity


  • Transcutaneous vagal nerve stimulation (tVNS) increases heart rate variability and alters cardiovascular autonomic control towards parasympathetic predominance
  • VNS causes a decrease in vasoconstrictor sympathetic nerve activity recorded using microneurography.
  • As sympathoexcitation is a hallmark of many conditions, including heart failure, tVNS may be a simple and inexpensive therapy for such conditions.
