Neural Networks Implicated in Autobiographical Memory Training.

Training of autobiographical memory has been proposed as an intervention to improve cognitive function. The neural substrates for such improvements are poorly understood. Several brain areas have been previously linked to autobiographical recollection, including structures in the default mode network (DMN) and the sensorimotor network.

Learning tasks as a possible treatment for DNA lesions induced by oxidative stress in hippocampal neurons.

Reactive oxygen species have been implicated in conditions ranging from cardiovascular dysfunc-tion, arthritis, cancer, to aging and age-related disorders. The organism developed several path-ways to counteract these effects, with base excision repair being responsible for repairing one of the major base lesions (8-oxoG) in all organisms. Epidemiological evidence suggests that cognitive stimulation makes the brain more resilient to damage or degeneration.
