How Computationally Complex Is a Single Neuron?

September 2, 2021

Computational neuroscientists taught an artificial neural network to imitate a biological neuron. The result offers a new way to think about the complexity of single brain cells.

The Complex Truth About ‘Junk DNA’

September 1, 2021

Genomes hold immense quantities of noncoding DNA. Some of it is essential for life, some seems useless, and some has its own agenda.

To Learn More Quickly, Brain Cells Break Their DNA

August 30, 2021

New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.
