Snake oil often resides on the apparent cutting edge of medical advance. This is a marketing strategy – exploiting the media hype that often precedes actual scientific advances (even ones that don’t eventually pan out). The slogan of this approach could be, “Turning tomorrow’s possible cures into today’s pseudoscientific snake oil.”
The strategy works because, to the average person, the claims will sound plausible and scientific and will contain familiar scientific buzz words. There is therefore a proliferation of stem cell clinics, anti-oxidant supplements, and personalized genetic medicine.
We can add to the list of cutting edge pseudoscience, neural plasticity and brain training. Neuroscientists are discovering that even the adult brain has greater capacity for plasticity than was previously thought. Plasticity is the capacity of the brain to rewire itself, to acquire new abilities or compensate for damage. Mostly this is simply a technical description of a very common phenomenon – learning. Shoot a basketball 1000 times and (surprising to no one) you (meaning your brain) will get better at shooting baskets. Some of this is physical, such as developing the necessary strength in the involved muscles, but mostly this is the brain learning how to shoot baskets through plasticity.
