“My research focuses on the analysis and maturation of neural networks, be they respiratory or cortical, physiological or pathological, in children and in animals. We have developed tools that make it possible to describe electric (EEG) and metabolic (NIRS) activities. Their modulations in pathological situations, as well as tracking the sources of these cerebral activities in children, and particularly prematurely so, are central to this research. In 2004, we created the GRAMFC, an innovation that allows simultaneous analysis of modifications in electric (High resolution EEG) local hemodynamic (High Resolution NIRS, Optical imaging) cerebral activity, both physiologically (cerebral maturation) and for pathological conditions (anoxic ischemia in premature babies, prenatal neurological suffering, and convulsions/epilepsy in children). With its combination of neuropsychologists, intensive care paediatricians, and signal processing experts, our research unit (EA4293) was recognized both in 2008 by the French Ministry of Research and in 2010 by the Inserm (U 1105).”

1. Schematic diagram of the functional NIRS (fNIRS). NIR-lights are generated and guided to the human’s head via optical fibers or cables. Another fiber bundle or cable directs diffusively reflected light from the head to detectors. A light detector captures the light resulting from the interaction with the chromophores (e.g. HbO, HbR), following a crescent-shaped path back to the surface of the skin. fNIRS takes advantage of the living tissue’s absorbing properties in the near-infrared range to measure changes in the local concentrations of oxy- and deoxy-hemoglobin ([HbO] and [HbR]) through intact skulls. Light in the NIR spectral range (650–950 nm ‘optical window’) can penetrate relatively deeply (a few centimeters) into the brain tissue, mostly because NIR light is only slightly absorbed by water, collagen, and proteins. fNIRS is performed by emitting near-infrared light into the scalp and detecting the transmitted light at certain positions.

2. EEG measures the sum total activity of the electrical signals that the brain sends to the scalp. EEG signals – as distinct from the fNIRS, which measures brain activity indirectly (i.e., changes in oxygenation) – are therefore generated directly through neuronal activity. The fNIRS’s spatial resolution is better than the EEG’s, and the EEG’s temporal resolution is better than the fNIRS’s

APPLICATIONS

Video of the dynamic appearance of NIRS results in a patient with epilepsy with a central initial focus that spreads in the frontal regions during an epileptic interictal spike.

EPILEPSY RESEARCH

Epilepsy involves complex mechanisms that combine neuronal, astrocytic, and vascular interactions, particularly within the neurovascular coupling involved in epileptic spikes and seizures.

The simultaneous analysis of various neuronal and vascular compartments by the EEG in tandem with the NIRS makes it possible to see the mechanisms involved and their interactions by a multimodal, multidimensional approach. Additionally, this simultaneous approach combines the EEG’s high temporal resolution with the high spatial resolution of the NIRS

COGNITIVE NEUROSCIENCE

The point of a wearable device for cognitive neuroscience that evaluates brain function in response to sensory stimulation lies essentially in the possibility of developing ecological stimuli that minimic everyday life situations in the best way possible. With a wearable device, it becomes possible to map out the brain structures involved in tasks such as driving or sports in real-life situations, as opposed to what is possible with fMRIs.

DBS/VSN

The appeal of the device lies in its compatibility with devices that involve electrical stimulation of the central (Deep Brain Stimulation (DBS)) or peripheral (Vagus Nerve Stimulation (VSN)) nervous system. This device thus makes it possible to map out the structures of the cortical surface that are modulated by these stimuli without having them be generated within the constraints of the electric fields produced by the stimulation or the constraints of magnetic fields inherent to MRIs and that make these maps difficult to produce in cases of DBS and VNS.
