Prospects and Problems of Brain Computer Interface in Healthcare

Abstract

Brain-Computer Interface (BCI) otherwise known as a Brain-Machine Interface (BMI) is an emergent technology whose goal is to create a real-time and direct communication pathway between the brain and external devices such as computers, robots, artificial limbs and wheelchairs. In BCI, cerebral or brain activities control these devices by transmitting and receiving signals from the brain. BCI is applied in healthcare to improve the communication capabilities of people living with disabilities or locked in syndrome such as traumatic brain disorders, Amyotrophic Lateral Sclerosis (ALS), spinal cord injury, brain stem stroke and other severe motor disabilities. BCI also increases the independence of disabled individuals by improving their muscle control. Consequently, BCI improves the quality of life of disabled persons by allowing this group of people to live a normal and comfortable life. In spite of the benefits of BCI, the technology is not widely deployed in healthcare. This is because of the numerous challenges associated with it. One of the basic limitations of BCI is that the signals received from the brain are prone to interference. Furthermore, legal and ethical concerns such as the risk of infection or hemorrhage, psychological

Care-receivers with physical disabilities’ perceptions on having humanoid assistive robots as assistants: a qualitative study

“…This feeling of eeriness has been described and named the “Uncanny Valley” by Mori (1970) [ 59 ]. Mori observed that robots appeal more to people with a human-like appearance, but only up to a certain point [ 59 , 60 ]. After reaching the uncanny valley, a person’s affinity decreases into a feeling of unease and a tendency to become scared.…”

Against Posthumanism: Notes towards an Ethopolitics of Personhood

“…As for augmenting our bodies and brains, a growing literature has shown that it is not necessarily so easy to live with ones prostheses (e.g. Davies and Dattta, 2003) and the use of brain/computer interfaces requires extensive training and is exhausting for the user over any long period (Olaronke et al, 2018). Many who have electrodes implanted for deep brain stimulation to modulate mobility problems cause by Parkinson’s, and now to ‘treat’ depression, ask for them to be turned off as they dislike the effects they have on their own sense of personhood (Bluhm et al, 2020; Dubiel, 2009).…”

BCI devices and their capacity to express human will having legal value: A model of risk-based classification

“…Lastly, BCI systems are exposed to possible misuse and cyberattacks, which can easily result in intentional or unintentional alteration of their functioning 18 .…”
