Neurons that fire together, don't always wire together

As the adage goes "neurons that fire together, wire together," but a new paper published today in Neuron demonstrates that, in addition to response similarity, projection target also constrains local connectivity.

Decoding how brain circuits control behavior

The mouse brain contains roughly 80 million neurons, all packed into a space about the size of a hazelnut. Those cells come in a vast assortment of shapes and sizes, and their connections with one another number in the billions—at ...

Neurons reliably respond to straight lines

Single neurons in the brain's primary visual cortex can reliably detect straight lines, even though the cellular makeup of the neurons is constantly changing, according to a new study by Carnegie Mellon University neuroscientists, ...

Diversity in the brain—how millions of neurons become unique

How is it possible that so many different and highly specific neuron types arise in the brain? A mathematical model developed by researchers from the University of Basel's Biozentrum demonstrates that different variants of ...

Engineers decode conversations in brain's motor cortex

How does your brain talk with your arm? The body doesn't use English, or any other spoken language. Biomedical engineers are developing methods for decoding the conversation, by analyzing electrical patterns in the motor ...
