TED Video: Ed Boyden: A light switch for neurons

In summary, Ed Boyden's TED Talk discusses using light to control neural activity in the brain. His "light switch" technology works by using optogenetics to activate or deactivate light-sensitive proteins in neurons. The potential applications of this technology are vast, including studying brain function and treating neurological disorders. However, there are challenges associated with its use, such as precise targeting and potential side effects. Overall, Ed Boyden's research has greatly advanced our understanding of the brain by providing a tool for precise manipulation of neural activity.

Interesting http://www.ted.com/talks/ed_boyden...._campaign=newsletter_weekly&utm_medium=email", I thought I would pass it on.

Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he's managed to cure mice of analogs of PTSD and certain forms of blindness. On the horizon: neural prosthetics.

Rhody... :wink:

Very interesting, thanks rhody!
 

1. What is the main concept of Ed Boyden's TED Talk?

The main concept of Ed Boyden's TED Talk is using light to control neural activity in the brain.

2. How does Ed Boyden's "light switch" technology work?

Ed Boyden's "light switch" technology works by using a technique called optogenetics, where light-sensitive proteins are inserted into neurons. These proteins can then be activated or deactivated by shining light on them, allowing for precise control of neural activity.

3. What are the potential applications of this technology?

This technology has a wide range of potential applications, including studying brain function and treating neurological disorders such as Parkinson's disease and epilepsy.

4. What are the challenges associated with using this technology?

Some challenges associated with using this technology include the need for precise targeting of specific neurons, potential side effects from prolonged light stimulation, and the ethical implications of manipulating brain activity.

5. How has Ed Boyden's research advanced our understanding of the brain?

Ed Boyden's research has advanced our understanding of the brain by providing a tool for precise control and manipulation of neural activity. This has allowed for new insights into brain function and has the potential to lead to new treatments for neurological disorders.
