sought to hire new staff that can pursue the system’s use in<br />
animal models.<br />
Strowbridge acknowledged that other methods are<br />
being researched as ways to avoid traditional electrodes.<br />
These include the exploration of biological systems that<br />
are light-sensitive; for instance, there is “a lot of excitement<br />
about genetic activation of brain cells.” But he said that this<br />
method is more complicated, would require a greater energy<br />
source and is more difficult to control.<br />
“Semiconductor particles” – by contrast – “offer much<br />
closer electronic access to the brain and have a very reliable,<br />
predictable response. That’s not so easy to get with<br />
biological methods,” Strowbridge said. But he said that<br />
whichever method proves more useful – and both may be<br />
quite serviceable, depending on the particular need, he<br />
acknowledged – an important intent will be to find ways to<br />
gather a larger, more accurate amount of neural data with<br />
less risk to patients than currently provided by standard<br />
electrodes. “The long-term goal of this work,” Strowbridge<br />
said, “is to develop a light-activated brain interface that<br />
restores function following nerve or brain impairments.<br />
Our findings may open up a whole new world of research<br />
possibilities.” The study was published in the journal<br />
Angewandte Chemie (Vol. 48, Issue 13, pp: 2407-2410).<br />
