Un implante cerebral traduce pensamientos en movimiento

Un implante cerebral desarrollado en la Universidad de Michigan (EE UU) usa la piel del cuerpo como conductor para transmitir, sin cables, las señales neurales del cerebro a un ordenador de control. El dispositivo podría usarse para reactivar los miembros paralizados.

El implante ha sido bautizado con el nombre deBioBolt y, a diferencia de otras tecnologías de interfaz neural que establecen una conexión desde el cerebro a un artefacto externo como un ordenador, requiere un mínimo de invasión y consume poca energía, dijo el investigador principal Euisik Yoon, profesor en la Escuela de Ingeniería, en el Departamento de Ingeniería Eléctrica y Ciencia de Computadora en la Universidad de Michigan.

BioBolt se implanta en el cráneo debajo de la piel y la capa de microcircuitos queda apoyada en el cerebro. Los microcircuitos operan como micrófonos que «escuchan» patrón general de activación de las neuronas y las asocian con un comando específico del cerebro. Esas señales se amplifican y filtran, se convierten en señales digitales y se transmiten a través de la piel a un ordenador externo.

Con los dispositivos disponibles hasta ahora el cerebro debe permanecer abierto mientras los implantes neurales están en la cabeza, lo cual impide en la práctica el uso diario en un paciente. BioBolt no penetra la corteza cerebral y queda completamente cubierto por la piel, lo cual reduce enormemente el riesgo de infección. Los investigadores creen que el artefacto es un paso muy importante hacia el objetivo último de las interfaces entre cerebro y computadora: permitir que una persona paralizada «piense» un movimiento.

«La meta es lograr la reactivación de los miembros paralizados» recogiendo las señales neurales de la corteza cerebral y transmitiéndolas directamente a los músculos, dijo Wise, quien es también director fundador del Centro NSF de Investigación de Ingeniería para Microsistemas Inalámbricos Integrados (WIMS ERC).No obstante, los investigadores advierten que el desarrollo de esta tecnología llevará años. Otra aplicación prometedora del BioBolt es el control de la epilepsia y el diagnóstico de ciertas patologías como la Enfermedad de Parkinson.

I found a sea shell and gave it to my 4 year old daughter and said «You can hear the ocean if you put this to your ear.» She placed the shell to her ear and screamed.

I was interested to find out how you center yourself and clear your head before writing. I’ve had a hard time clearing my mind in getting my thoughts out. I truly do take pleasure in writing however it just seems like the first 10 to 15 minutes are usually wasted simply just trying to figure out how to begin. Any recommendations or hints? Cheers!

  3. There are some interesting closing dates in this article but I don�t know if I see all of them center to heart. There is some validity but I will take hold opinion until I look into it further. Good article , thanks and we want more! Added to FeedBurner as well

  4. You nailed it. I had an Eldon track figure eight and did precisely the same. Taped the control to set the speed of the other car and raced to catch it. Hrs spent with that track. Believe I will go out and set up my track once again and get off this PC for the even though and make some laps
