Lighting up the brain.

A little preamble: This week I wrote a guest post for another neuroscience blog. I talked about one of my favorite topics: optogenetics, the technique to control your neurons by shining a laser on them. Sounds like something Iron Man would do -- but is actually done by scientists in labs all over the world. Read on and enjoy!

In 1979, Nobel laureate Francis Crick mused about how wonderful it would be to find a way to control just one type of brain cells while leaving others untouched1. Twenty years later, seeing all the shortcomings of electrophysiology (low precision in targeting cells) and pharmacological manipulations (too slow in comparison to real neurotransmission), he went one step further and suggested that light might be the answer we’ve been looking for. The idea of switching neurons on and off like lightbulbs sounded both crazy and appealing, yet no one knew how to approach it. It took another six years for things to get real. Optogenetics was on its way.

Memory and the manipulations thereof.

Have you ever envied Kate Winslet’s character in the “Eternal Sunshine of the Spotless Mind”? Have you ever wished that you could erase memories of a nasty ex just by pushing a button? (I sure did after one of my exes told me that trees have souls whereas I do not) Or that you could bring an elusive memory back into your head? (I bet everyone who has ever written an exam sure did). Basically: Would you like to manipulate memory?

New kid on the (news) block: Neuroscience news

So not only did I create a fancy new website, I also decided to spice it up a bit more. *Intense drumroll* From now on I will do a bi-weekly news block to keep you updated on what awesome stuff has been discovered in neuroscience while we all were struggling through the week. On the menu this week: magic mushrooms and depression, what happens in your brain when you talk to God, and memory enhancement by brain manipulation.
