Imaging to help people with brain injuries

cerveau, brain

People with brain injuries have complex cognitive and neurobiological processes. This is the case for people who have suffered a stroke, or who are in a minimally conscious state and close to a vegetative state. At IMT Mines Alès, Gérard Dray is working on new technology involving neuroimaging and statistical …

Technology that decrypts the way our brain works

Electroencephalogram: a brain imaging technique that is efficient but limited in terms of spatial resolution.

Different techniques are used to study of the functioning of our brain, including electroencephalography, magnetoencephalography, functional MRI and spectroscopy. The signals are processed and interpreted to analyze the cognitive processes in question. EEG and MRI are the two most commonly used techniques in cognitive science. Their performances offer hope and …

Mathematical tools for analyzing the development of brain pathologies in children

MRI

Magnetic resonance imaging (MRI) enables medical doctors to obtain precise images of a patient’s structure and anatomy, and of the pathologies that may affect the patient’s brain. However, to analyze and interpret these complex images, radiologists need specific mathematical tools. While some tools exist for interpreting images of the adult …

The brain: seeing between the fibers of white matter

Neural Meta Tracts, brain, white matter, Pietro Gori

The principle behind diffusion imaging and tractography is exploring how water spreads through our brain in order to study the structure of neurons. Doctors can use this method to improve their understanding of brain disease. Pietro Gori, a researcher in image processing at Télécom ParisTech, has just launched a project …

The brain: the mechanics of convolutions

Croquis cerveau

Why do our brains have so many folds? The answer to this question is far from simple. In fact, the answer only came at the beginning of 2016, from a team of researchers including members from Harvard University and Télécom Bretagne. Unlike some of the theories previously proposed, this answer …
