Genetic 'GPS' System to Comprehensively Locate and Track Inhibitory Nerve Cells Created

ScienceDaily (Sep. 21, 2011) — A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has succeeded in creating what amounts to a GPS system for locating and tracking a vital class of brain cells that until now has eluded comprehensive identification, particularly in living animals.

Thanks.

But let's wait others' opinions.

Comprehensive also has the meaning of covering all aspects, and in such a context, can mean placing something beyond all doubt, as all aspects have been considered.

Cool.
Thanks.
What does identification mean there?

It means the identification of specific brain cells as belonging to the class of brain cells referred to.

So specific? Like identifying a person in your workshop as the employer or an employee?

@oristarA,

It's as specific as that class of cells are described in the article, which i'm not going to take the time to read. Now, based on the context which you provided, the class of "brain cells" (it actually says, initially, nerve cells) are inhibitory cells--cells which prevent something from happening. Based on the context you have provided, that is how specific it is.

By the way, the use of the term comprehensive implies that specificity is being sought. The researchers seek a means which will identify that class of cells, and that class of cells only--hence, they seek a comprehensive means of identifying the cells.

@oristarA,

Key text with respect to the word "comprehensive"

Quote:

"Optogenetics and retroviral labeling are wonderful techniques, but they are not, by themselves, cell-type specific. We've built a system that integrates all of these technologies, which can now be mobilized with exquisite specificity," Huang says.
The net result is a toolkit -- which will grow to include more mouse lines -- for the use of experimentalists in labs everywhere, and which enables comprehensive and systematic exploration of inhibitory GABA neurons
