Have you seen the movie “Inside Out” yet? The movie takes place inside the brain of an 11-year-old girl, Riley, with different characters playing the role of various emotions (joy, anger, sadness, etc.).
Rather than sending out signals with parceled bits of information about the direction and size of movement, Shenoy’s team found that groups of neurons fired in rhythmic patterns to get muscles to act.

A team of Bio-X scientists applied microscopy know-how to a long-standing theory in neuroscience: if brain connections called synapses store memories, those synapses should last as long as the memories themselves. It turns out they do, as Mark Schnitzer was able to show.
If you find yourself forgetting information you have only your synapses to blame. These connections between neurons are what hold on to memories.
How do we reverse-engineer the most mysterious organ?
Before digital brains can interact with the world, they will need to see and understand their environment and their place in it. All this requires is digitizing several hundred million years of evolution.
Understanding the brain's mechanics isn't enough to reverse-engineer a functional copy. What's needed is a theory of how those pieces add up to a human being.
The neurons in our brains use electrical activity to relay information. A reverse-engineered brain must recreate these processes, but first scientists need to understand them.
The brain is a powerful natural computer, processing millions of signals on the power of nothing more than a sandwich. To reverse-engineer it, you need to mimic that speed and efficiency.
When people are confronted with an unknown piece of electronics, one way they can figure out how it works and what it does is to twiddle with the knobs and switches. That's been hard to do with the slick, knob-less surface of the brain.
