Non-Invasive Neuromodulation

Is the application of safe, evidence-based technologies that administer light, sound, electrical stimuli directly to the nervous system or specific brain areas, such as cerebral blood flow and electrical current flow via a feedback loop. The training & treatment serves as a way to effect enduring change and corresponding improvements in functioning and quality of life.

Here’s a snapshot of some training & treatment modalities Brain Optimax offers.

HEG Biofeedback


HEG is a modality that specifically trains the prefrontal cortex in order to enhance concentration, impulse control, planning, organising, sequential processing, etc.

The frontal region of the brain is known as the “executive brain” and the “control centre”, with interconnected neurons to other vital parts of the brain. Poor blood oxygenation in the area has been shown in literature to be associated with autistic features, ADD/ADHD, depression, and schizophrenia.

In a HEG session, near or passive infrared sensors are used to detect and display blood flow dynamics on a monitor in real-time, allowing the trainee to effect positive change. By increasing blood oxygenation, metabolism is encouraged in the associated cortical area, leading to optimal functioning. HEG training has been evidenced to be efficacious in various clinical conditions such as migraine, depression, ADHD, learning difficulties, perception issues, cognitive issues, obsessive compulsive tendencies (OCD), Autism, seizures and mild-to-moderate head trauma.

(Transcranial Direct Stimulation)

tDCS is used in various clinical conditions, such as speech difficulties/delay, cognitive issues, stroke, epilepsy, and depression.

tDCS is a non-invasive direct current stimulation modality used to stimulate specific cortical area(s) according to individual treatment objective. The training aims to optimise the neuronal activation beneath the area treated, hence enhancing function. Positive stimulation will enhance activation of the area and used when there is under-activation. Conversely, negative stimulation decreases activation and is applied when there is over-activation.


(Audio Visual Entrainment)

AVE has been used to treat depression, anxiety, chronic pain, sleep issues, and addiction.

AVE uses repetitive light and sound stimuli to “free” the brain, which facilitates ease entry into states that promote attention, relaxation, meditation, creativity, and amelioration of anxiety and stress.

AVE has been evidenced by research to support learning, memory enhancement and boosts the body’s immune system by increasing dendrite growth. AVE can also improve athletic performance by increasing the brain’s efficiency under pressure.
