NCT00842413

Brief Summary

This project aims at understanding better the role of the frontal lobe of the brain in our capacity to perceive visual information consciously, and also, in our capacity to perceive others' actions. It includes a test where we ask subjects to detect visual information in front of a computer screen, and another test where we ask them to imitate finger movements.

1

The study compares brain-damaged patients with healthy ones on two psychophysical tasks.

2

The study does not intervene on the brain-damaged patients, it merely compares their behaviour with that of healthy patients on a range of psychophysical tasks.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The visual pereption of subjects willl be studied, but no attempt will be made at modifying it, or treating any problem that they might have.

You may qualify if:

  • Healthy subjects chosen from a pool of adult subjects, recruited through ads.
  • In the second group, the subjects are recruited from a pool of brain-damaged patients treated at the hospital de la Pitié-Salpétrière. They must suffer from a focal lesion in the prefrontal cortex.

You may not qualify if:

  • For the healthy group: any previous brain-related medical history.
  • Widespread brain-damage, extending beyond the prefrontal cortex, that is to say, lesions that are not really focal.
