Neuroethics

In the Twilight of Aging, a Twinkle of Hope - Part 1

Issues: 

The arrival of grey hairs can signify both the attainment of wisdom and the accumulation of age. In the words of Solomon of old, grey hair "is a crown of splendor; it is attained by a righteous life."(Proverbs 16:31, NIV) Grey hair is also a visible reminder of the uncertainty of maintaining mental faculties in old age. For many people, the prospect of deterioration in brain function is feared more than any other ailment of aging. Joints may give way and vision dim without eroding personal integrity. The brain, however, is essential to who we are. Its grey matter is the centerpiece of the living tapestry of personal identity.

Grey Matters: Can Grey Voxels Resolve Neuroethical Dilemmas? Part I

Issues: 

Part II

Advances in noninvasive medical imaging have opened new windows into the living brain. Like observatories pointed inward, modern brain scanners routinely capture breathtaking images of the gyral swirls and neuronal clusters that underlie human cerebral nature. These brain portraits are composed of three-dimensional voxels, or volume picture elements, digitally displayed in shades of grey.

The Wisdom of the Synapse: From Patterns of Neuronal Transmission to Principles of Human Communication

Issues: 

The synapse refers to the intercellular junction where chemical information is transmitted fro one neuron to another. This paper will examine the natural patterns of information flow at the synapse as a small scale paradigm for considering both constructive and pathological forms of communication among human communities.

Materias grises: Cuando la elocuencia es incoherente

Issues: 

Los franceses tienen una expresión -je ne sais quois- que se refiere a una cualidad atractiva indescriptible. Existe, por ejemplo, además de la meta de lograr aptitud en los procedimientos, un cierto algo que atrae a las personas a campos como la bioética. Algunas de las razones de la fascinación que uno tiene con una disciplina encuentran expresión en términos racionales, mientras que otras podrían estar más allá de la comprensión del lenguaje explícito. Como la atmósfera evocada por una melodía vagamente conocida de origen olvidado, es el "no sé qué" que subyace la característica inexpresable de las aspiraciones personales de una persona.

Grey Matters: Glimpsing the Grey Marble

Issues: 

Quiet as an eyeblink clicked the camera shutter from the window of Apollo 17.  Astronauts Cernan, Evans, and Schmitt on December 7, 1972 captured the first clear and fully illuminated image of Earth ever taken from space.  This historic and widely circulated “Blue Marble” photograph of our fragile globe, depicted in vibrant blue, green and white and suspended in the vast blackness of silent space, has stirred the imagination of a generation.

Una mirada a la Bolita Gris

Issues: 

Silencioso como un parpadeo, el obturador de la cámara accionó desde la ventana del Apollo 17. Los astronautas Cernan, Evans y Schmitt capturaron el 7 de diciembre de 1972 la primera imagen clara y plenamente iluminada que se haya tomado jamás de la Tierra desde el espacio. Esta fotografía histórica y de amplia circulación, denominada "Blue Marble" (Bolita o Canica Azul) de nuestro frágil globo, representado en un azul, verde y blanco vibrantes y suspendido en la vasta negrura del espacio silencioso, ha estimulado la imaginación de una generación.

Materias grises: La iluminación del gris

Eric Kandel, investigador pionero de los mecanismos moleculares de la memoria, comentó una vez: "Somos quienes somos en gran medida por lo que hemos aprendido y lo que recordamos"[1] Si la materia gris forma la urdimbre y la trama de la biografía, la individualidad, la racionalidad y la capacidad creativa personal, ¿debemos concluir entonces que todo lo que podamos hacer para aumentar la función cognitiva nos convertiría en mejores personas?

Grey Matters: The Matter of Brightened Grey

Eric Kandel, pioneer investigator of the molecular mechanisms of memory, once commented, "We are who we are in good measure because of what we have learned and what we remember.1 If grey matter forms the warp and woof of personal biography, individuality, rationality and creative capacity, does it then follow that whatever we can do to augment cognitive function would make us better persons?

Grey Matters: When Eloquence Is Inarticulate

Issues: 

The French have an expression—je ne sais quois—which refers to an indescribable attractive quality. There is, for example, in addition to the goal of attaining procedural competence, a certain something that draws people to such fields as bioethics. Some of the reasons for one’s fascination with a discipline find expression in rational terms, while others may lie just beyond the grasp of explicit language. Like the mood evoked by a faintly familiar melody of forgotten origin is the je ne sais quoisunderlying the inexpressible feature of one’s personal aspirations.
