Brain Therapy Centre specialises in the assessment and treatment of brain function.
Neurofeedback therapy involves measuring and training the electrical signals generated by the nerve cells of the brain. These signals, called EEG, are related to the efficiency of information processing and show how effectively the different parts of the brain are operating.
What is Neurofeedback ?
Neurofeedback works by teaching a person to produce more optimal EEG patterns using positive reinforcement. During a neurofeedback session, the client is connected to EEG sensors that measures their brain activity. The sensors are connected to a computer, and the EEG signals are used to control a simple computer game.
The game provides the client with feedback about their brain’s activity. When their brain produces more optimal activity the game will start, which rewards the client for successfully changing their EEG. When their brain produces less optimal activity the game will stop, which removes the reward. By repeatedly rewarding optimal activity, the client’s brain learns how to produce more of the optimal activity and less of the sub-optimal activity.
Who Can Benefit From Neurofeedback ?
Neurofeedback can be used to treat a wide variety of psychological conditions in people of all ages. Neurofeedback can be used to treat anxiety, depression, stress, ADHD, insomnia, chronic pain, substance abuse, stress, headaches, Post-Traumatic Stress Disorder and brain injury.
Neurofeedback can also improve functioning in people with developmental disorders such as Autism Spectrum Disorder, learning problems, and intellectual disabilities. Neurofeedback can also be used to improve the peak performance of musicians, executives, and athletes.
What is EEG ?
The electroencephalogram (EEG) is a measurement of the electrical activity of the brain. The nerve cells, or neurons, communicate by ‘firing’ tiny electrochemical signals from one cell to the next. These signals travel through the skull, and cause tiny electrical fluctuations in metal sensors placed on the scalp. By the time the neural signals reach the scalp they have dropped in amplitude to around 10 millionths of a volt! These electrical fluctuations are then amplified, and displayed on a computer.
The EEG appears as a wavy line, and shows the electrical fluctuations caused by the synchronised firing of groups of neurons. The placement of the sensors on the scalp determines which parts of the brain are measured.
This raw EEG can be mathematically divided into different waveforms, which represent different kinds of firing patterns. These different firing patterns, in general terms, represent different levels of brain activation. Smaller, faster waves such as Beta represent greater activation, whereas bigger, slower waves, such as theta, represent lower activation. There are correlations between brain activity patterns and cognitive and behavioural functioning.
For example, Attention Deficit/Hyperactivity Disorder (ADHD) has an EEG ‘signature’ that shows excessive slow wave activity in the frontal and central parts of the brain. This means that these brain areas are processing information less efficiently, which can cause problems with regulation of attention and physical activity.
Conditions We Treat
- ADHD (Hyperactive and/or Inattentive)
The value of neurofeedback as a non-medication treatment for ADHD is well documented. Read More >
- Anxiety Disorders
Anxiety is a term used to describe the physical sensations associated with the body's fight-or-flight response. These often include rapid heart-rate, sweating, difficulty breathing, and dizziness. Read More >
Depression is a psychological condition characterised by low mood, poor motivation, low energy and loss of interest in enjoyable activities. Read More >
Addiction is characterised by compulsive seeking of rewarding stimuli, despite negative consequences. Addictions come in many forms, such as alcohol or drugs, gambling, food, and video gaming. Read More >
- Post-Traumatic Stress
Experiencing traumatic events can lead to changes in functioning. Post-traumatic stress disorder (PTSD) is an anxiety disorder characterised by repeated, intrusive memories of traumatic events. Read More >
- Chronic Pain
Pain is a complex physical and emotional response to injury. There are a great number of factors that influence a person's experience of pain. Read More >
Headaches are the experience of pain in the head and neck. Headaches are among the most commonly experienced physical discomforts. Read More >
Insomnia is a disorder affecting sleep. It can affect sleep onset, sleep maintenance or sleep quality. Read More >
- Brain Injury
Brain injury can cause a wide range of difficulties with functioning. Brain injuries can be caused by external events such as a blow to the head, or by internal events such as stroke. Read More >
- Autism Spectrum Disorder
Autism Spectrum Disorder (ASD) is a developmental disorder affecting around 1.5% of the population. Children and adults with ASD experience difficulties with communication and social interactions, and often also experience sensory sensitivity and anxiety. Read More >
- Improving Cognitive Performance
Neurofeedback has been found to be effective in improving the cognitive functioning of children and adults. Read More >
