EyeBrain, a company developing medical devices for the early diagnosis of neurological diseases, announces today that its EyeBrain Tracker device is being used in a clinical trial exploring the dyskinesia induced by treating patients suffering from idiopathic Parkinson’s disease with levodopa.
The endpoint of the trial is to find biomarkers for the late-onset complications of a treatment regime using levodopa (BIODYS). This compound, which is naturally transformed into dopamine in the brain, is one of the only drugs available for slowing the effects of Parkinson’s disease. However, over time, it induces dyskinesia in these patients, which takes the form of abnormal movements primarily affecting the face (tongue, lips, jaw) and extending as far as the arms and legs.
Altogether, 30 people will be enrolled on the trial. Half of them will be Parkinson’s sufferers who have been treated with levodopa and have developed dyskinesia, while the other half will consist of healthy subjects who will be used as a control group.
The trial is being sponsored and financed by Bordeaux University Hospital and was set up by professor Jean-François Tison, a neurologist attached to the CNRS Physiopathology of Parkinsonian syndromes unit at the University of Bordeaux Two (the Institute of Neurodegenerative Diseases, CNRS UMR 5293E, Bezard). The EyeBrain Tracker device is being funded under the joint 2007-2013 State-Region Plan (Aquitaine Regional Council and the FEDER fund).
“Patients suffering from idiopathic Parkinson’s disease will undergo an acute test as part of a pre-operational assessment for stimulating the deep recesses of the brain,” explained professor Tison. The motricity effects of the treatment will be evaluated by measuring the speed of eye movements with the help of the EyeBrain Tracker.
“We will see whether levodopa modifies the parameters of blinking in a way that is correlated with the improvement in motricity,” said professor Tison. “Using the EyeBrain Tracker enables us to measure the motricity effect through eye movements, since the blinking parameters are also linked to the patient’s general motricity. The patient’s response to this trial is also a predictor of their reaction to the neurosurgery that will follow.”
The EyeBrain Tracker, which is already used in the early diagnosis of Parkinsonian syndromes, such as progressive supra-nuclear paralysis (PSP), cortico-basal degeneration (CBD) and multiple systems atrophy (MSA), is thus continuing to broaden its fields of application. It is now playing an important role in clinical research into other neurological diseases, such as multiple sclerosis, and is a valuable aid in the early diagnosis and follow-up of these diseases.
“We are delighted to know that the EyeBrain Tracker is playing a part in a clinical trial targeting idiopathic Parkinson’s,” said the chairman of EyeBrain, Serge Kinkingnéhun. “This forms part of our goal of making the benefits of eye motricity available to a larger number of people suffering from neurological pathologies.”
Parkinson’s disease is the second most common neurodegenerative disease after Alzheimer’s. In western countries it affects 0.3 per cent of the general population. Its prevalence increases with age, reaching one per cent in the over-60s, and as much as four per cent in the over-80s. There are 100,000 sufferers in France and 8,000 new cases are diagnosed each year.About EyeBrain
The Mobile EyeBrain Tracker (EBT) comes as a complete solution including headphones, a computer with two screens and stimulation and analysis software. It is already being used routinely in hospitals to help with the early characterization of Parkinsonian syndromes. Studies are also underway for the diagnosis of multiple sclerosis (MS).
The Mobile EBT is the only device of its kind in the world to have obtained CE marking. The company has ISO 9001 and ISO 13485 certification.
EyeBrain, which is based in the Paris suburb of Ivry-sur-Seine, was founded in 2008 and currently employs 15 people. It has raised funding of EUR 1.2 million from the CapDecisif and G1J venture capital funds and already generates revenues through the sale of the EyeBrain Tracker. It is engaged in collaborations with the French National Health and Medical Research Institute (INSERM), the French National Scientific Research Center (CNRS), Paris University Hospitals group, the University of Paris-Descartes and the French Brain and Spinal Cord Institute.For further information about the company, go to: http://www.eye-brain.com

Highly precise wiring in the Cerebral Cortex
21.09.2017 | Max-Planck-Institut für Hirnforschung
Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
