Effect of Omega-3 Phospholipids on Perceptual-cognitive Training

Omega 3 in the form of phospholipids are the main component of nerve cells and their oral intake is known to have a positive impact on behavior disorders such as depression or bipolar disorder. Their consumption would improve brain function while increasing the ability to concentrate. The study aims to determine the effect of an increase in Omega 3 in the form of phospholipids on the processing of visual information in the brain and in particular the attention and perceptual-cognitive learning in a three dimensions environment. Eighty subjects (40 young (18-35 years) and 40 older (60-75 years)) divided into four groups, two Omega-3 (20 young and 20 older) and two other placebo (20 young and 20 elderly ), will in this study, performing a complex perceptual-cognitive task such as the pursuit of moving objects in a 3D space. This stimulus was chosen because it is very similar to the situations of daily life, but also because it involves a mechanism of perceptual-cognitive level. The main objective is to demonstrate the positive effect of Omega-3 phospholipids on the perceptual-cognitive training.
