SELF SUFFICIENT MONKEY'S BRAINS


Diverse evidences come demonstrating that the human brain will become in some moment self-sufficient, condemning human body and senses in redundant and/or dispensable. Event to be materialized when the brain orders and correctly direct -with only the thought- to organic or robotic arms -at distance-. During the animal evolution, the senses built the brain, having been that, their final goal. Now the brain doesn't need them -at least in the usual way-. The self-sufficient brain, also traffics for the possibility that receptors similar to cloroplasts, capture solar energy directly, transforming it into cerebral electric impulses. The reproduction could be carried out by means of clonatión of nervous cells (that’ s to say: brains) and cerebral glia.

A step in such a sense are some kind of experiments called : brain/machine/interface that for but of 30 years diverse scientists of the world carry out. Recently 2 hungry monkeys (Macaca mulatta), with 100 small electrodes (width equal that of a hair), inserted in 100 primary cortical brain neurons in charge of controlling body movements, learned how to control a mechanical arm with alone the power of the thought (electric waves of small power), to catch food in order to self-eating. Event that could have application in injuries to human spine and other paralyzing illnesses, bypassing affected neural ways related with the movement (William Heetderks, Managing National Institute of Biomedical Imaging and Bioengineering). Previously some humans were able to control the cursor of a computer, using alone their cerebral waves. Andrew Schwartz, professor of Neurobiology of the University of Pittsburgh, adds that this experiment was successful due to the extraordinary cerebral cortical plasticity, allowing neuroprosthesis be implanted in the brain.

CEREBRO DE MONOS, AUTOSUFICIENTES.

Diversas evidencias vienen demostrando que el cerebro humano devendrá en algún momento en autosuficiente, condenando al soma y los sentidos en redundantes y/o prescindibles. Suceso a materializarse cuando el cerebro ordene y dirija correctamente con el pensamiento a brazos orgánicos u, robóticos, a distancia. Durante la evolución animal, los sentidos construyeron al cerebro, habiendo sido esa su meta final. Ahora el cerebro no los necesita –al menos al modo usual. La autosuficiencia cerebral transita también por la posibilidad de que receptores semejantes a cloroplastos, capten directamente energía solar, convirtiéndola en impulsos eléctricos cerebrales. La reproducción podría realizarse mediante clonación de células nerviosas (entiéndase cerebros) y glia cerebral.
Un paso en tal sentido son los experimentos brain/machine/interface, que desde hace mas de 30 años realizan diversos científicos del mundo. Recientemente 2 monos macacos hambrientos, con 100 pequeños electrodos (del ancho de un pelo), insertados en 100 de sus neuronas cerebrales corticales primarias encargadas de controlar el movimiento, aprendieron a controlar un brazo mecánico con solo el poder del pensamiento (ondas eléctricas de pequeña potencia), para coger comida y autoalimentarse, lo cual podría tener aplicación en injurias de la médula espinal y otras enfermedades paralizantes bypasseando señales relacionadas con el movimiento (William Heetderks, Director National Institute of Biomedical Imaging and Bioengineering). Anteriormente, algunos humanos lograron controlar el cursor de una computadora, empleando tan solo sus ondas cerebrales. El Dr. Andrew Schwartz, profesor de Neurobiologia de la Universidad de Pittsburgh..añade que esto será posible por la plasticidad cortical cerebral, permitiendo el implante de neuroprótesis.

It's genuinely very complicated in this full of activity life to listen news on Television, therefore I only use internet for that purpose, and take the most up-to-date news.

Review my web site ... www.Bizdenet.Com
