Scientists at Baylor College of Medicine have discovered 53 neuron cells in the small bird's brain that may actually make up a biological "GPS system," each with its own characteristic response to the Earth's magnetic field. The combined data of each neuron's reaction to its north-south and up-down orientation gives the pigeon not only an accurate compass heading, but may also give it coordinates on a mental map.

“We use the same cells to build a sense of self, since these cells originate early in life when other people’s behavior is the reflection of our own behavior. In other people, we see ourselves ...

Neuroscientists have discovered how the sense of touch is wired in the skin and nervous system. The new findings open new doors for understanding how the brain collects and processes information from hairy skin.

Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he's managed to cure mice of analogs of PTSD and certain forms of blindness. On the horizon: neural prosthetics.

New connections between brain cells emerge in clusters in the brain as animals learn to perform a new task, according to a new study. The findings reveal details of how brain circuits are rewired during the formation of new motor memories.

What is a Neural Network?

Firstly I want to point out that yes, it is a brain.

Inspiration and interpretation are inevitable. As metaphor is basic to what we do, so emerging results in neuroscience will be taken well beyond the intentions and even meanings of their authors. Much caution and critique will be needed. Yet at the same time, I want to preserve a space for this other mantle, from science to art and humanism. To creation and design and expression.

A revolution based on neuroscience? No. A recognition of our bodies and experiences and senses? Yes. And thus much closer to metaphors that inspire us every day. Like HOME or WARMTH. And maybe even a tree or two.
