These techniques have also permitted deeper insights into human pathologies and have enabled major advances across diverse scientific disciplines. This section of the website will first present the latest neuro-scientific research primarily pertaining to ADHD. It will then progress to discuss the essentiality of specific brain selective nutrients and their role in neurodevelopment. The final section presents some of what we know so far in relation to the potential implications of nutritional deficiencies in the brain.
