Technology · neurofeedback, tDCS, CES, taVNS, tPBM
One circuit. Several technologies. A single routine for the brain.
You don't come for a device. You come for the NeuroFit experience. Here you'll find what each device does and what science says about it.
NeuroFit uses five non-invasive technologies: tPBM (photobiomodulation with near-infrared light), NeurOptimal® neurofeedback, taVNS (vagus nerve stimulation through the ear), CES (cranial electrotherapy stimulation) and tDCS (transcranial direct current stimulation). They are combined into circuits for the Focus, Relax, Reset and Longevity experiences, after a safety screening. NeuroFit is brain wellness and does not replace medical treatment.
The brain changes with experience.
Neuroplasticity is the brain's ability to adjust its connections according to what it lives, repeats and learns. Every habit leaves a trace.
That's why, at NeuroFit, repetition matters more than the intensity of a single session. The gym works the same way.
Light for brain wellness.
Red and near-infrared light applied non-invasively, through devices worn on the head. The light does the work. No current, no sensations.
The most studied mechanism: certain wavelengths are absorbed by cytochrome c oxidase in the mitochondria, an enzyme involved in producing cellular energy. Research has investigated the effects on energy metabolism, cerebral blood flow and cognitive performance.
See the research →Real-time brain feedback.
NeuroFit uses NeurOptimal®, a dynamic neurofeedback system. Sensors placed on the scalp read electrical activity while you listen to music. When the system detects sudden changes in activity, the music briefly pauses. The brain receives the information and uses it in its own way.
Neurofeedback is based on a learning principle: when it receives information about its own activity, the brain can self-regulate. NeurOptimal® does not aim to increase or decrease particular EEG waves. It gives feedback about changes, without a targeted protocol.
See the research →From the ear to the brain.
A small device, with an electrode shaped like an earbud, sits in the cavity of the outer ear, the area reached by the auricular branch of the vagus nerve. The device sends very gentle, low-frequency electrical impulses through the skin to the nerve fibres beneath it. The intensity is set individually, below the discomfort threshold, so you feel at most a slight tingling or pulsing. During the session you sit relaxed, with your eyes open or closed.
The vagus nerve is one of the main communication pathways between the body and the brain. Stimulating the auricular area activates afferent fibres that carry the signal to the brainstem and, from there, to brain networks involved in regulating attention and calm.
See the research →A moment for reset.
Two electrodes in the form of soft clips attach to the earlobes. The device emits an alternating microcurrent, in the range of millionths of an ampere, far below the intensity used in other forms of stimulation. Most people feel nothing, or only a discreet tingling around the ears; if dizziness appears, the intensity is reduced. A session usually lasts 20–60 minutes, during which you can relax, read or listen to music.
Microcurrent is investigated for its ability to modulate neural activity. Research has explored CES in contexts such as relaxation, sleep and anxiety. These are areas investigated in research, not NeuroFit medical services.
See the research →Modulating cortical excitability.
Two electrodes with sponges soaked in saline solution are positioned on the scalp, in a configuration set according to the target area. The device sends a constant, weak direct current of 1–2 mA between them for about 20–30 minutes, ramping up and down gradually at the start and end. The current does not trigger nerve impulses; it slightly changes the activation threshold of neurons in that area. Under the electrodes you may feel a slight tingling, itching or warmth, usually in the first few minutes.
The weak electric field does not directly trigger nerve impulses, but slightly changes the excitability threshold of neurons in the cortex. The effect depends on electrode position, intensity and duration, and is studied in relation to brain plasticity.
See the research →Not all five, in every session.
Your circuit is a combination of technologies chosen according to the experience, eligibility, screening, contraindications and safety. It may include one, two or more technologies. Some may be excluded completely.
The example is illustrative only. The actual circuit is set individually, after screening.
Studied doesn't mean guaranteed.
Research results depend on several factors and don't automatically transfer from one study to any individual:
- The population studied
- The protocol used
- The device
- Duration
- Stimulation parameters
- Replication of results
When we mention research on depression, anxiety, sleep or pain, we are talking about areas investigated in science, not about NeuroFit medical services or promises.
