You can improve your brain function by engaging in regular physical activity, learning new skills, eating a healthy diet and getting plenty of sleep. Which is great, but it’s all a bit boring.

What CrowdScience listener Mariana from Mexico wants to know is whether the sort of brain augmentation she’s seen in sci-fi could soon become reality.

Along the way he interrogates the ethical implications of the breakneck speed of progress in brain augmentation research.
