COVID-19 update – Our clinics are open and we’re taking bookings Read more

We are now taking bookings for our Harley Street clinic. You can use our online booking system or phone 0800 030 6617 to talk to an administrator.

Our other clinics around the country are open, so please contact us to find out when the earliest appointment at your preferred clinic will be.

During appointments, our clinicians and audiologists are working in a safe manner to reduce infection and help you recover from your tinnitus. We clean surfaces between patient appointments in line with Government guidance and that issued by the British Society of Audiology.

We will require you to answer a few questions before you come into clinic to minimise the risk of spreading COVID-19 infection.

Remember, if you're unable to attend a clinic we run a full telecare service with remote assessments and fittings using video through our e‑consult service.

Scientific Principles

The Brain

The brain consists of approximately 100 billion nerve cells (so-called neurons); each neuron is connected to approximately 1,000 other neurons. The result is a giant network with billions of connection routes that are used to convey messages and information through the brain to control our entire organism. Like a computer, neurons form switching circuits, whereby different switching circuits have different tasks. For instance, some switching circuits are for storing information, whilst others are responsible for processing signals. Neurons communicate with each other via electrical signals – that is why brain activity can be examined by measuring brain waves (EEG = electroencephalography) or the electrical fields produced by the brain (MEG = magnetoencephalography).

Synchronous nerve cell activity and neurological diseases

In principle, neurons that belong to the same switching circuit can "fire" simultaneously or asynchronously. This differs depending on the process or activity. There are certain diseases where the asynchronous nerve cell assemblies of a switching circuit suddenly start to synchronise: the neurons are permanently and excessively engaged in synchronous activity and they all fire at the same time. It is this pathologically synchronised "firing" that causes the typical symptoms – the tremor of Parkinson's and the phantom sound of tinnitus.

Pathologically synchronous activity and natural synaptic plasticity

Unfortunately, some neurological diseases are accompanied by the sudden occurrence of pathologically "enhanced" synchronous activity of a nerve cell assembly that is the start of a vicious circle:

The brain's natural synaptic plasticity causes the pathologically synchronous neurons to strengthen their connections

The stronger the network between the cells, the better the synchronous alignment!

The result is the occurrence of defective processes in the brain that lead to the formation of highly synchronous neuronal networks with pathologically enhanced connections. The brain has learned "pathological firing".
