For more than a century, researchers have known that people are generally very good at eyeballing quantities of four or fewer items. But performance at sizing up ...

Memristors, or memory resistors, are components that adjust their resistance based on past electrical activity, effectively storing a memory of it. While most existing memristors are solid-state ...

Computers could mimic neural networks in the brain -- and be much more energy efficient -- with a new computer component that mimics how the brain works by acting like a synaptic cell. It's called an ...

A new study by physicists and neuroscientists from the University of Chicago, Harvard and Yale describes how connectivity among neurons comes about through general principles of networking and ...
