Which Way to the Brain Gym?
Intelligence is classically thought of as an immutable characteristic of each individual, pre-determined by genetics and permanent for a person’s entire life. But what if this is not true? It is an appealing idea to think that somehow, one can voluntarily, and naturally, boost his or her level of cognitive performance. Research has already shown that the brain is more plastic than originally thought. Parts of the hippocampus, a subcortical brain structure implicated in tasks of memory and other cognitive control functions, as well as the olfactory bulb (smell center) have been shown to generate new neurons after initial neurogenesis in the mammalian brain. These findings play into the idea that there is a way to somehow become smarter, even though you aren’t necessarily born with such cognitive gifts.
There are now apps and other computer programs that claim to improve brain function with excessive use. One of the bigger names in this field, Lumosity, runs advertisements that their brain-training program is backed by research and is “based on neuroscience.” The purpose here is not to discredit such apps like Lumosity and Brain Fit, but to take a closer look at the legitimacy of these claims of cognitive improvement, examine some actual research being done, and encourage a critical approach to a topic that popular culture REALLY wants to be true.
