NCT ID: NCT03998930 Completed - Stroke Clinical Trials

Evaluation of Consciousness by Brain-computer Interface in Severely Brain Damaged Patients

AWAKE
Start date: March 6, 2018
Phase: N/A
Study type: Interventional

The objective of this study is to show that the measurement of auditory and vibro-tactile evoked potentials, or the recording of the EEG signal during a motor imaging task, can be used in routine clinical situations to explore the state of consciousness of subjects in Non-responsive Awakening (or Chronic Vegetative State) or in Minimal Consciousness (or relational state) after a severe brain injury. Assumptions : - Correlation between patient response rates obtained with the brain-machine interface and their clinical consciousness score (Coma Recovery Scale Revised score) - Differentiation of the parameters of the evoked potentials P300 between patients in a vegetative state and those in a state of minimal consciousness

NCT ID: NCT02482571 Completed - Brain Hypoxia Clinical Trials

Metabolic Changes in the Activated Human Visual Cortex During Mild Hypoxia

Start date: August 13, 2015
Phase: N/A
Study type: Interventional

The primary objective of this research is to measure changes in neurochemical concentrations during stimulation of the primary visual cortex, in both conditions of normoxia (normal oxygen availability) and induced mild hypoxia (reduced oxygen availability).

NCT ID: NCT01614119 Completed - Hypoxia Clinical Trials

Cerebral Responses During Exercise in Hypoxia

CERVOX
Start date: June 2010
Phase: N/A
Study type: Interventional

While the exercise responses are classically described at the cardiorespiratory and muscle levels, recent data suggest that the brain is also significantly stressed by exercise and may even participate to performance limitation. In hypoxia in particular, cerebral responses to exercise may be altered and promote performance reduction during endurance exercise. In the present study, the investigators used innovative approaches to assess cerebral perturbations associated with exercise in hypoxia.
