Neurotherapy techniques can help identify which parts of the brain are running optimally, and where the brain may struggle, treating mental health disorders as a supplement to talk therapy or medication.

Neurostimulation or Non-invasive brain stimulation (NIBS), is an active intervention utilizing the addition of a stimulus to entrain the brain to produce certain wavelengths, increase energy, or reduce inflammation utilizing a variety of technologies including: 

tECS (Transcranial electrical stimulation) is a non-invasive brain stimulation technique that passes an electrical current through the cortex of the brain to alter brain function. This innovative approach encompasses several modalities, including transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), transcranial random noise stimulation (tRNS), and Vagus Nerve Stimulation (VNS). The technique operates at subthreshold levels, modifying neuronal excitability without directly triggering action potentials

tDCS (Transcranial Direct Current Stimulation) tDCS is a non-invasive treatment for modulating brain activity with minimal side effects. It uses very low levels of electrical currents applied to the scalp that targets specific areas of the brain in order to enhance brain activity, often producing profound results. tDCS enhances rehabilitation in neurological conditions by promoting neuroplasticity and improving motor/speech function when combined with therapy. 

tACS (Transcranial Alternating Current Stimulation) is similar to tDCS as a neuromodulatory technique, but instead of applying a direct electrical current, tACS oscillates a sinusoidal current at a chosen frequency to interact with the brain’s natural cortical oscillations.

tRNS (Transcranial Random Noise) or Noise/ Acoustic therapy is a non-invasive noise stimulation that can increase synchronization of neural firing by amplifying the oscillatory activity and reducing the amount of internal noise particularly in the Brown Noise and Pink Noise frequencies.  If a signal is too weak to induce action potential generation and random noise is added, the improvement of the signal can lead to enhanced cognitive performance.

VNS (Vagus Nerve Stimulation) The vagus nerve is the longest in the body and controls various functions including digestion, heart rate, breathing, and the immune system. When activated, the VNS device generates low-energy electrical signals, transmits these signals through the vagus nerve which disperses these signals to different areas of the brain. This process alters brain cell activity, potentially calming areas of abnormal electrical hyperactivity. 

Pulsed Electromagnetic Field (pEMF) has been around for decades and has been used by scientists around the world to study the effects of pEMF on organs and disease in the body. There are over 2,000 published clinical studies that show the benefit of pEMF on many different conditions.  NeuroField’s FDA approved device is an ultra-low intensity, pulsed electromagnetic field (pEMF) unit that works to replenish energy and reduce stress in the brain and body. pEMF is purely electromagnetic and does not introduce direct current to the skin. The brain and body will “mimic” the pEMF fed into it and capillary blood flow will increase. Inflammation can limit the success of other types of biofeedback, pEMF can reduce inflammation and be given at fast speeds without generating heat and damaging tissue. pEMF can be used to entrain the brain via Operant conditioning or dis-entrain the brain via de habituation.

NeuroField’s pEMF has been documented as an intervention for insomnia, Parkinson’s disease, premenstrual dysphoric disorder, attention deficit disorder, anxiety, conduct disorder, and posttraumatic stress disorder. It has been shown in clinical studies to be an effective intervention for many other conditions and symptoms. Follow-up with the subjects of the studies and the clinical population has suggested that the changes hold over time.

Photobiomodulation (PBM) is a form of neuromodulation using LED light therapy at various wavelengths, typically Red Light Therapy (RLT) or Near Infrared Light Therapy (NIR) to improve brain functioning. NIR therapy is a type of phototherapy that uses light in the near-infrared spectrum to promote healing and reduce inflammation. It's a non-invasive treatment that can be used for a variety of conditions, including skin rejuvenation, pain management, and even some neurological conditions. Numerous research studies confirm the benefits of light therapy in treating many mental health and physical conditions including depression, anxiety and even Alzheimer's.  In essence, red light therapy eliminates that lack of energy that accompanies low mood and anxiety. Red light therapy is known to increase the efficacy and integrity of mitochondria – the ‘powerhouse’ of the cell. This energy is then distributed where it is needed the most. One of the ways NIR may support your mental health is by stimulating areas of the brain that are linked to certain types of depression and anxiety. Namely, dlPFC and vmPFC play critical roles in the pathophysiology of depression. With well-calculated exposure to RLT and NIR, it is possible to modulate appropriate brain areas, so you can treat and improve the depression and anxiety symptoms.
