Did you know scientists have mapped mammalian neural microcircuits in precise detail ?


Neuroscientists at the Francis Crick Institute have developed a new technique to map electrical microcircuits* in the brain at far more detail than existing techniques*, which are limited to tiny sections of the brain (or remain confined to simpler model organisms, like zebrafish).

In the brain, groups of neurons that connect up in microcircuits help us process information about things we see, smell and taste. Knowing how many neurons and other types of cells make up these microcircuits would give scientists a deeper understanding of how the brain computes complex information.

Nanoengineered microelectrodes

The researchers developed a new design called “nanoengineered electroporation** microelectrodes” (NEMs). They were able to use an NEM to map out all 250 cells that make up a specific microcircuit in a part of a mouse brain that processes smell (known as the “olfactory bulb glomerulus”) in a horizontal slice of the olfactory bulb — something never before achieved.

To do that, the team created a series of tiny pores (holes) near the end of a micropipette using nano-engineering tools. The new design distributes the electrical current uniformly over a wider area (up to a radius of about 50 micrometers — the size of a typical neural microcircuit), with minimal cell damage.

No, I didn't, and that's really a good deal.
They'll be able to determine exactly how our brain processes information from our senses.
I'm thinking that would be useful for studying schizophrenia and other neurological disorders.
I would think this would be helpful in creating robots with senses as well.
We're pretty good at mimicking, when we want to be.
