New neurons continue to be formed in the hippocampus into the tenth decade of life, even in people with mild cognitive impairment and Alzheimer’s disease.
A recent study has shown that religious fundamentalism is partly the result of a functional impairment in the prefrontal cortex, where damage to particular areas may indirectly promote religious fundamentalism by diminishing cognitive flexibility and openness.

Our brains are continuously bombarded with information from the senses, yet our level of vigilance to such input varies, allowing us to selectively focus on one conversation and not another.
Researchers have discovered it is possible to use soundwaves and viruses to ‘switch off’ memory formation in the brain.
