What is the latest in bioethics?
One of the buzzwords of bioethics in the next few decades will likely be “neuro”. When I was in medical school, we were told that little is known about how the brain works. However, neuroscience has gained a lot of knowledge in these last 30 years because of the advances of imaging techniques coupled with powerful computer technology.
The tremendous progress on understanding how the human brain works can revolutionize our comprehension of ourselves and our society. Hence, there are important ethical implications on how to apply this new knowledge.
I belong to a study group called “neurobioethics” based in Rome that consists of philosophers, ethicists, psychologists, psychiatrists, neurosurgeons, neurologists, radiologists and theologians, because it is necessary to approach this difficult subject from many angles. I will mention some of the emerging questions of neurobioethics today below.
Some scientists are trying to map the human brain using supercomputers to understand the thought process. Human thinking is a very complicated process, with many parts of the brain and different neurons firing and receiving message. Imagine that each of your brain cells (neuron) is assigned to an individual laptop computer, and a million of these computers are linked together to see how these neurons communicate in every thought. Then, it is possible to find out what happens in the brain when we see colors, hear a song, feel, remember, think, get angry, happy, or sad.
Neuromarketing measures consumer preferences by means of neurological testing. For example, one can measure brain activity of someone watching an advertisementin order to see how effective it has been.
Could neuroimaging techniques one day allow us to read other’s thoughts, or be used as a polygraph to test if someone is lying?
Knowledge gain from neurosciences can help doctors study brain diseases, and perhaps correct them. One day, this knowledge can be used to combat diseases such as Autism or Attention Deficit Disorder. Studies are being carried out to learn how the brains of psychopaths, criminals, and terrorists work. There are already methods of cognitive enhancement to improve one’s memory, concentration, wakefulness, and IQ. Could we one day even use this to eliminate bad memories, fear, or violent tendencies? Could we even modify our moral sense?
Obviously, some of these techniques can be problematic, as they violate our rights to privacy, informed consent, and personal identity. New laws would have to be enacted to protect citizens, for example, in the use of information obtained from our brain scans in hospitals.
One important issue that emerged is the way we define ourselves. I think there is a tendency to reduce our humanity to the brain as a complicated computing machine. We are spiritual and moral beings, and there are many things—such as love, joy, courage, sacrifice, heroism—that could not be examined under the microscope or explained by the most powerful Magnetic Resonance Imaging (MRI) or CT scans.
Recently, I attended a two-day conference at Oxford University called “Neurosociety. What is it with the brain these days?” where many of these issues were discussed. Most of the participants were surprised to see someone dressed as priest in this gathering. One of them approached me and asked, “Why is the Vatican interested in this?” Since in the conference, we just heard that neuro has become the new prefix for everything, like neurowater, neuroeconomics, neurolinguistics, I told him tongue and cheek that I was there because I was interested in “neurotheology”. He was stumped.
Of course, I was only kidding. Well, sort of.

Or, perhaps, “Cardioneurotheology”? 😉 God bless!
I like it! Too much head, not enough heart (or vice versa) nowadays. The Gospel has to reach both. God bless!
Science fiction has been exploring the issues of philosophy and ethics and technology since Frankenstein, and the conclusion is always that, while science is good, not all technology is consionable. Yet today we have to explain why all over again to promoters of transhumanism and other high-tech bad ideas.
When they take God out of the picture, or take on the role of god themselves, this always becomes the problem. New Evangelization has to reach the technological sector too, but mostly, we need to reach the hearts of men and women. More God, for everyone!
Neuromarketing Reminds of “The Hidden Persuaders” by Vance Packard, 1954 – a visionary
I’m vaguely familiar with this, Carl. There’s a lot of truth to it — not necessarily a happy truth for the manipulated unawares.
Every step we take in understanding the creation of the human body is just amazing. As an RN I was taught the miraculous systems and circuitry of the body and how they all work together to maintain life at the ultimate state of health: homeostasis.
if only scientists and all physicians could see this research the same way, there would be no need of bioethics panels, which I fear are not so successful by my own experiences.
Great blog post.
I know what you mean. Bioethics panels, according to my experience, are not always formed by people with any experience or competence in ethics or medicine. So although the “opinion of a bioethics panel” may suggest an expert opinion, the truth is more often than not that this is not the case. It usually ends up justifying a means to a more pragmatic or economical approach, with little regard for the human person whose well-being depends on their weakly informed decisions.
