Genetic background, epigenetic factors and dietary interventions which influence human longevity.

abstract：:Ageing can have profound effects on the post-mitotic organ of behaviour, the brain. As yet the precise causes of these deleterious effects are unknown. However, clear insights into the putative mechanisms and consequences of ageing in the CNS have been achieved through the use of invertebrate models. It is now clear t...
