Neuroethics Journal Club: The Ethical Issues behind Brain-to-Brain Interface (BTBI) Technologies

Image
The first Neuroethics Journal Club of the Fall 2013 semester was a discussion led by graduate student John Trimper on the ethical implications behind brain-to-brain interface (BTBI) technologies. John introduced the topic by presenting the experimental details and results from a recent paper, published by the Nicoleis lab at Duke University (Vieira et al.), where researchers utilized a BTBI to transfer sensorimotor information between two rats. The BTBI technology allowed for a transfer of information from an “encoder” rat to a “decoder” rat, not using typical bodily interactions, but instead through intracortical microstimulation (ICMS). "Rodent Mind Meld" (Via Wired) The researchers conducted three experiments that demonstrated an artificial communication channel where cortical sensorimotor signals, coded for a specific behavioral response, were recorded in the encoder rat and transmitted to the decoder rat. Once received from the encoder rat, the decoder rat was instructed...

Tibetan monastics and a neuroscientist: Some lessons learned and others taught

Image
By Guest Contributor Brian Dias, PhD Imagine your day starting out near the Northern Indian town of Dharamshala with thirty minutes of spiritual chanting and meditation among Tibetan Buddhist monastics. Now you follow that by spending the whole day teaching Neuroscience to these same monastics. “Bliss”, “introspection”, “questioning”, “challenging” and “why” are some of the words that may come to mind. They certainly did for me while I had the privilege of being a Neuroscience faculty member as part of the Emory Tibet Science Initiative (ETSI) this past summer in India. Other faculty members included Dr. Melvin Konner (Evolutionary Anthropology, Emory University), Dr. Ann Kruger (Developmental Psychologist, GSU) and  Dr. Carol Worthman (Medical Anthropology, Emory University). An audience with His Holiness The XIV Dalai Lama, and teaching monastics in Dharamshala, India. I intend to use this blog post to shed light on the intersection of Buddhist philosophy and western science ...

Gearing Up for New Currents in Sports Enhancement

By Anjan Chatterjee, M.D., F.A.A.N Anjan Chatterjee is a Professor of Neurology at the University of Pennsylvania.  His clinical practice focuses on patients with cognitive disorders. His research focuses on spatial cognition and language, attention, neuroethics, and neuroaesthetics. He is President of the International Association of Empirical Aesthetics and the Chair of the Society for Behavioral and Cognitive Neurology . He is also a member of the AJOB Neuroscience editorial board. Alex Rodriguez is the latest in a long list of superstar athletes embroiled in a doping scandal. Lance Armstrong, Tyson Gay, Barry Bonds, Marion Jones, and Mark McGuire, among many others, preceded him. Competition in sports is predicated on athletes following rules; rules that try to codify fairness. Some combination of natural talent and effort is rewarded. Each athlete strives and may the best man and woman win. Despite this ethos, doping scandals abound. Almost a third of the athletes...

Consciousness and Ethical Pain

Image
Imagine you find that a beloved uncle has received a terrible injury that leaves him paralyzed, but still totally aware of his environment - a condition known as locked in syndrome . Now imagine that a doctor comes to you with a miracle cure: a new experimental treatment will repair your uncle's damaged brainstem allowing him to regain control of his body. The catch, however, is that this procedure is extremely painful. It actually seems like it might be the most painful experience possible: fMRI scans reveal that all the brain regions that are active during extreme pain are activated during this (imaginary) procedure. And it lasts for hours. However, your uncle won't complain about the procedure because 1) he's paralyzed and thus can't voice his suffering, and 2) the experience of this miracle treatment will mercifully be forgotten once the procedure is over, so your uncle won't raise any complaint afterwards. While many of us would probably sign off on the procedu...

2013 Neuroethics Scholar, Jen Sarrett: Autism and the Communication of 'Risk'

Image
The Neuroethics Scholar Program By Jennifer C. Sarrett This project is done through The Neuroethics Scholar Program As defined in the new Diagnostic and Statistical Manual of Mental Disorders (DSM 5), Autism Spectrum Disorder (ASD) is diagnosed in individuals who show differences in social communication—such as a reliance on non-verbal communication techniques or difficulties interpreting social signals—and specific behavioral patterns—such as repetitive vocal or motor behaviors or intense interests in specific items. These characteristics must be evident before the age of 3 in order to quality for an ASD diagnosis 1 . While there are diagnostic tools that are able to reliably diagnose ASD by the age of 2, most reports show that, on average, children are not diagnosed until school age. These rates vary by several factors, including race and urbanicity 2 . For many professionals, this delay in diagnosis is concerning because, as the Centers for Disease Control and Prevention 3 and m...
