The development of techniques for recording and stimulating neural activity has produced a revolution in the ability to understand the cognitive mechanisms related to perception, memory, attention, and the planning and execution of actions.
However, whether or not these techniques can realistically be used for cognitive augmentation depends not only on how effective they are at detecting interpretable neural activity and/or stimulating specific target areas of the brain, but also on a number of other relevant factors. doi: 10.1109/86.847815 Pub Med Abstract | Cross Ref Full Text | Google Scholar Kennedy, P.
Among these is the degree of invasiveness—i.e., to what extent a technology requires introduction of instruments into the body—as well as other practical factors, including how portable or expensive technologies are, which influence their usability in everyday life for human cognitive augmentation.
In the following sections we will review these technologies with their pros and cons.
Such processes encompass attention, the formation of knowledge, memory, judgement and evaluation, reasoning and computation, problem solving and decision making, as well as the comprehension and production of language.
