I hope it is already clear why the previous eight posts have been devoted to Stanislas Dehaene’s “Consciousness and the Brain: Deciphering How the Brain Codes our Thoughts,” but, nevertheless, I shall briefly elaborate here. Simply put, using our conscious mind effectively is key to a healthy memory. One of the primary goals of meditation (for example, the relaxation response), is to gain control of our attention rather than either ignoring our brains’s potential, or letting our brains run wild.
Growth mindsets encourage us to use the global workspace of our brains, to think and to learn new information and skills. This activates those neurons in the prefrontal cortex with the long axons reaching far into different parts of the brains. I strongly believe that this activity strongly promotes brain health. It is likely that it is largely responsible for the cognitive reserve that is cited as the reason that the autopsies of many individuals reveal the neurillary fibers and amyloid plaques that provide a definitive diagnosis of Alzheimer’s, yet these individuals never indicated any of the behavioral or cognitive symptoms of Alzheimer’s.
It is clear that there is enormous activity of the brain, but we can gain access to only a small percentage of this activity. So how can we increase the probability that our unconscious minds are functioning productively? A good way of thinking about this is that our conscious mind is, or should be, the chief executive of our brain. Think of the brain as an enormous enterprise that we supervise. The unconscious mind uses what we think about consciously as a guide to at least some of its unconscious activity. A good example of this is when we try to remember a name or a word, but successful retrieval fails (remember the distinction between available and accessible memories). It is not unusual that many hours, sometimes even a day a more later, the desired item pops into consciousness. So even though you gave up trying to remember, your unconscious brain kept working on this task. My favorite problem solving technique is incubation. This is done when you give your mind a rest and stop working on the problem. Although your conscious mind has stopped working, your unconscious mind perseveres, and the solution seems to pop into your mind unsummoned. There are documented cases of important discoveries that have been made in this manner. Thee are probably many more that have not been discovered or articulated.
So meditate to achieve better control over your consciousness. Also pursue a growth mindset. Review previously acquired knowledge and continue to pursue new knowledge. Also give your unconscious mind something to mull over, such as a problem to solve, or an apparently lost memory to recover. As was mentioned in a previous healthy memory blog post, with the exception of the most trivial decisions, it is best to allow time for your conscious mind to run simulations and reveal unrecognized problems (see the healthy memory blog post, “Let Me Think it Over).
