Transcranial Direct Current Stimulation


tDCS has a wide variety of clinical applications including cognitive enhancement and the treatment of many neuropsychiatric conditions including

  • Depression

  • Anxiety

  • TBI (Traumatic Brain Injury)

  • OCD (Obsessive Compulsive Disorder)

  • Insomnia

  • Parkinson’s

  • Language disorders

  • Visual Improvements

  • Movement disorder


This shows cognitive performance improvements after tDCS – the white box is from sham tDCS (placebo), and black is the active tDCS. The different tests include:

  • StC, StW, StIC: measure complex focus and sustained attention

  • DSF and DSB: measure attention and working memory capacity

  • SD: processing speed

  • FP: Test of verbal fluency

tDCS: Transcranial Direct Current Stimulation is a form of neuromodulation in which a constant, low voltage, direct current is applied to the brain via two surface sponges/electrodes: an anode and cathode. 


This current enters the brain at the anode, travels through brain tissue, and exits via the cathode. Positive stimulation from the anode causes depolarization of the neuron's resting membrane potential, which increases neuronal excitability. When the cathode is placed on the brain, this negative stimulation causes hyperpolarization and has an inhibitory effect. Throughout treatment, this electrical stimulation modulates neuronal activity through the regulation of pyramidal neuron excitability, glucose consumption, and cerebral blood flow.


Here you can see our founder, Joe Castellano, using the Neurofield stimulation system.

Your qEEG assessment allows our team to develop a protocol specifically for your brain as over and under-active areas of the brain and disturbances in neural circuitry are identified. This non-invasive, painless, and safe therapy results in lasting changes in cortical excitability and increased neuroplasticity via the selective disruption of neuronal activity patterns that contribute to your symptoms.
