Brain-computer interfaces are systems that allow for communication between the brain and some other device, typically for the purpose of recording electric signals or restoring/altering functionality in a user. For example, they are often used for paralyzed individuals to use artificial limbs or to enable communication.
Joe Vukov is a philosophy professor at Loyola University with an extensive knowledge of bio and neuroethics. He was recently able to give a talk surrounding brain-computer interfaces (BCIs) and their surrounding ethics. More specifically, he discussed a study in which neurostimulation was used to respond to loss of control eating in the article “Brain-Responsive Neurostimulation for Loss of Control Eating: Early Feasibility Study.” The study focuses on the use of a closed loop BCI in order to detect signals correlated with negative eating patterns prior to overeating and disrupt the process. The main concern regarding this form of treatment is whether or not patients will have true autonomy and consent over when these urges are controlled. Vukov pointed out that systems such as these could serve as an inhibitor of one’s decision making ability as patients are not fully able to stop treatment on a whim should they decide they would no longer wish to continue. Vukov went on to propose different ideas for future work with BCIs, such as those that could be controlled with a button for a patient to decide when they would like a response to be activated or not.
In more advancements, researchers are working towards using these methods of stimulation for work related to strokes and neurodegenerative diseases. One article discussing such progress is “Advances in Brain–Computer Interfaces (BCI): Challenges and Opportunities”. The article goes into detail about proposed and ongoing work relating to these interfaces and what is in store for the future. For example, long-term use of BCI electrical stimulation has shown to increase neuroplasticity in older patients who experienced strokes. Another study mentioned in the article focused on tracking sleep staging. BCIs are shifting in such a way that they are able to provide more modulatory impacts on neural circuitry over simply reading brain activity as well, allowing for more clinical uses of the technology. Researchers are also looking into further use for emotion recognition and disease detection. With all of these new advancements, the potential uses of these interfaces are endless.
The work being done by researchers is critical for the understanding of the possibilities for the clinical use of BCIs. From disease detection to enhancement of neuroplasticity, there are many directions in which this technology can be taken in order to aid those in need. While there is much work surrounding the abilities of these interfaces, there is less discussion on the ethical concerns that come with. Vukov’s discussion on privacy concerns and the autonomy of the patient is imperative in ensuring proper patient choice and understanding of these brain computer interfaces. While there are functions that may be critical, there still must be some level of autonomy for patients when deciding how these BCIs will function, and who all of the collected data will belong to or who has access to it. Vukov went in detail about potential motor discrimination and user-activation possibilities that may be implemented with design. With all the advances in clinical uses of BCIs, making sure that each user can maintain individuality and choice will be of utmost importance for researchers to consider in future work.
