The brain reacts to everything it comes into contact with, this includes stimulus from the senses and internal processes such as those created during meditation. Recent scientific studies indicate that brain structure and function can be positively meditated by methods such as Brain Renewal Meditation (BRM).
One of the big deals with cognitive decline is we don’t really understand how it works. There is of course an inevitability that human brain performance must eventually decline, it is unrealistic to assume brain structure can remain intact for eternity. But as a command and control system the human brain is unrivaled in the universe. We are currently unable to count the billions of neurons in a human brain, and mankind still doesn’t have the computing power to run a biologically reliable digital simulation of our brain, even if such a model could be created. What we do know is that the brain is able to develop new function and structure (plasticity) and there is some evidence that new neurons can be generated in the adult hippocampus (neurogenesis).
The ability of the brain to restructure makes understanding brain aging particularly problematic. Structures are continually changing, new functions require support and obsolete functions can fall into decay. These changes take place against a backdrop of an incalculable amount of stimulus, almost everything we experience or think about can have an impact on the brain. The average rate in the reduction of human cognitive function is generally referred to age related cognitive decline. The factors linked to ‘typical’ rates of decline are still not fully understood and the nuanced way that structures change and interact is far from clear.
The idea that from the age of thirty adults lose a little bit more of cognitive function every year is completely wrong. Whilst cognitive decline is correlated with age, regional and global improvements in brain function during middle and old age have been observed.
From the point of view of meditation, we know from traditional sources and modern science that certain forms of meditation exert an effect on different regions of the human brain. Long term meditators have been found to have ‘younger’ brains than non meditators and meditation is also associated with increased cortical thickness. Meditation is not the only way of maintaining or increasing brain health but it is one of the oldest and most reliably established. The message is pretty simply, if you want to maintain or improve brain age or brain health think very seriously about meditation.
