Stripping down science, the naked scientist on Sunday, November the 21st, and that's with me Chris Smith.

And with me, Sarah Sarah Costa Perry. Now this

week boosting your brain power drugs are available that can increase concentration

improve memory and fight fatigue and they're increasingly being used by students

who are pulling all nighters before exams by business people with pitches to perfect

and by academics with deadlines to beat. But how safe are these cognitive equivalents of anabolic steroids for the brain, and is it fair

or ethical to use them?

Will universities ultimately end up screening students for these drugs in the same way that athletes are tested at the Olympics.

Well, what do you think we'd very much like to hear your opinions?

Indeed, and we'll also get an update from the 2010 neuroscience conference that's been taking place this week in

San Diego and it's included presentations on approaches to overcome blindness

by working out exactly how the eye communicates with the brain.

The eye does essentially take a picture,

but then it goes much further.

It processes the picture.

It extracts information from it,

and then it converts that information into a code

that the brain can read.

So to make an effective prost prosthetic device you've really

got to have both these functions and I think we really have this now. We have both of these

components. If you'd like to get in touch with us through Twitter you can tweet
