Transcranial direct current stimulation (tDCS) is a wearable, portable brain stimulation technology that delivers low electrical current to the scalp, meaning that tDCS is a neuromodulation technique that produces immediate and permanent changes in brain function. The anode and negative electrode position on the head is used to determine how current is flowing to specific areas of the brain. The current delivered by tDCS is not strong enough to release an action potential in a neuron. Instead, the sub-threshold actually changes the electrical pattern of the neurons. The thought in the brain as being active while trying to do something or teaching it like this comes the role of tDCS to reinforce this ongoing activity at the cellular level. TDCS alters the firing of neurons and by enhancing the synaptic transmission between neurons by increasing synaptic plasticity
What does a tDCS device look like?
Small devices powered by batteries. There is a control panel that allows you to program the device (to set the duration and intensity of stimulation). The electrodes are placed on the head and held in place by the head cover – usually a rubber band – the cable of each electrode is attached to the stimulator
When the alarm is turned on, current flows from the device to the electrode and then crosses the brain
Our professional grade catalysts have many features that help ensure stimulation and reliability including an impedance meter and ammeter.
What are the side effects of direct transcranial stimulation?
The side effects that have been fixed so far are minor, limited to the site of the electrode, and include:
Temporary redness of the skin
Itching
Twitching
Headache
Nausea
Dizziness
It should be noted that these last three side effects have been reported to occur at approximately the same rate as placebo stimulation when tDCS is administered insufficiently.
How does tDCS feel?
People feel a slight tingling, itching or warmth. These sensations are not painful and disappear when the stimulation stops
What are the benefits of tDCS?
TDCS is used for many different applications that involve changing the brain to affect how people think or feel
Depression
Schizophrenia
Aphasia
Addictive
Memory enhancement
TDCS has been proven to make people learn faster, and it also uses rapid education, focus, relaxation and meditation

Can tDCS treat anxiety?
The effects of tDCS have been shown to reduce anxiety in several clinical trials from top medical centers
Can tDCS treat depression?
Several clinical trials have reported that tDCS can treat depression, and it has fewer side effects than drugs
