This is interesting:
A team at Stanford University has made brains transparent, allowing entire networks of neurons to be highlighted and then viewed through an optical microscope. They claim that the technique works with other organs of the body.
The findings are published in Nature as Structural and molecular interrogation of intact biological systems (PDF). It’s not an easy read, but the images are colourful and illuminating. It ends with the claim that this technique ‘provides access to structural and molecular information that may help to support integrative understanding of large-scale intact biological systems’.
As an aside: ‘We’re heading into the centre of a mouse’s brain, into the hippocampus, where memories are formed‘. This statement is worthy of our attention.
And finally, just to remind ourselves that there’s more to a mouse than a brain, this is the sound of a deer mouse.
