Neurotechnology and the Military

“Every generation has been trying to figure out how to use brain-related technology to improve security,” from caffeine to computer enhancement, bioethicist Jonathan Moreno, Ph.D., said at the Capitol Hill briefing “Neurotechnology and the Military” last week. Moreno and neuroscientist Leigh Hochberg, M.D., Ph.D., had teamed up to give a similar presentation at a luncheon six years ago, and on Friday the two brought us up to date.

Thanks to a half-century of federally funded basic research, researchers have developed a chip carrying 144 electrodes that can be inserted into people’s skulls (over the motor cortex) and send impulses to computers to drive a cursor or a mechanical object, said Hochberg, the director of the Center for Neurotechnology and Neurorecovery at Massachusetts General Hospital and a professor at Brown University and Harvard Medical School.

Neuroethics Society Meeting: Science Communication

Tali Sharot, Alan Leshner, Joseph Fins, and Ed Yong

Gone are the days when science communication mainly consisted of publishing in peer-reviewed journals. Instead, there’s a “hunger” among scientists, and particularly young scientists, to communicate their work to public, said Alan Leshner, CEO emeritus of the American Association for the Advancement of Science (AAAS) and a member of the Dana Alliance for Brain Initiatives (DABI).

But just because the enthusiasm is there doesn’t mean that communicating science to a lay audience is an easy feat for scientists. “It’s not an innate skill, it’s an acquired skill,” Leshner said during a panel discussion at the International Neuroethics Society annual meeting yesterday in Washington, DC.   Continue reading

Neuroscience and Society: To Tell the Truth!

Elizabeth Loftus, Charles Dike, and Victoria Talwar

In the animal kingdom, humans have the unique distinction of being the species that tell lies, which researcher Victoria Talwar describes as “verbal statements made with the intention to deceive.” An emphasis is placed on the word “intention” because this is what distinguishes lies from other false statements, such as mistakes or sarcasm. During a Neuroscience & Society program held this week in conjunction with the International Neuroethics Society’s annual meeting, Talwar described her work on the development of understanding behind truth and lying in children. Fellow panelists Elizabeth Loftus focused on the malleability of human memory and how this affects honesty, while Charles Dike described the layers of many questions behind pathological liars and the distinctions this type of lying has from others.

One point all three speakers shared is that lying is a normal part of life; it follows stages of cognitive development and persists into adulthood. Adults tell an average of one lie a day, said Talwar and Dike.

Truth and lying are complicated neurological behaviors. Although the role of the visual cortex and other areas of the brain are being identified, and their functions clarified, it is not likely that there is a “truth” center in the brain or a “lying” center. Scientists try to identify neurological correlates of truth-telling and lying in the laboratory, but it is not known if any findings of this type are operative in real life. This program will examine three important real-life aspects of truth and lying.

First, are we born with the ability to understand the concept of truth and lying? Victoria Talwar will discuss the childhood development of a sense of lying and truth-telling. Second, do our “minds” know what is true and what is false? Elizabeth Loftus will describe the phenomenon of so-called repressed memories and how it is possible for someone to be convinced they are telling the truth when they are not. Finally, what do we know about people who are consistent liars? Charles Dike will explore the nature of pathological lying and why some people lie seemingly without purpose.
