Abstract
The brain–computer interface (BCI) has made remarkable progress in the bridging the divide between the brain and the external environment to assist persons with severe disabilities caused by brain impairments. There is also continuing philosophical interest in BCIs which emerges from thoughtful reflection on computers, machines, and artificial intelligence. This article seeks to apply BCI perspectives to examine, challenge, and work towards a possible resolution to a persistent problem in the mind–body relationship, namely dualism. The original humanitarian goals of BCIs and the technological inventiveness result in BCIs being surprisingly useful. We begin from the neurologically impaired person, the problems encountered, and some pioneering responses from computers and machines. Secondly, the interface of mind and brain is explored via two points of clarification: direct and indirect BCIs, and the nature of thoughts. Thirdly, dualism is beset by mind–body interaction difficulties and is further questioned by the phenomena of intentions, interactions, and technology. Fourthly, animal minds and robots are explored in BCI settings again with relevance for dualism. After a brief look at other BCIs, we conclude by outlining a future BCI philosophy of brain and mind, which might appear ominous and could be possible.

Notes
If the neural signals proceed to a machine such as a robot and not to a computer, the term BMI was used (Donoghue 2008). The terms are nowadays interchangeable. Other terms are neural interface systems (Hatsopoulos and Donoghue 2009), and neuroprosthetics which uses neural interface systems to control robotic limbs to perform three-dimensional movements (Hochberg et al. 2012; Kwok 2013). All BCI systems require some type of training: learned voluntary control or cognitive voluntary modulation (Birbaumer and Cohen 2007). In this article, we use BCI for convenience.
The anonymous author anticipates the question: “So why am I writing this piece anonymously? Because I don't want to be known to the scientific community as 'Parkinson's guy' before I am known as a scientist” (p.30). The article notes that the author is a neuroscience professor at a major university in the USA and that he blogs at parklifensci.blogspot.com and tweets at @Parklifensci. e-mail: parklifensci@gmail.com.
These interesting comparative titles were suggested by an anonymous reviewer, who likens the situation to “being in the mind of someone” and “trying to infer what is happening in the mind”. We return to this in the conclusions.
The existence of a range of applications and indeed status between BCI being a “‘means” and a “machine subject” was highlighted by an anonymous reviewer together with a helpful suggestion.
