Until recently, neuroscientists thought humans were born with all their neurons. Now they knowyour body actually continues to build your brain throughout your life, starting at birth and continuing as you age. Over time, your brain cells form and store more memories and feelings, allowing you t...
“How the brain is organized to help make decisions is a big, fundamental question, and the neural circuitry — how neurons are connected to one another — in brain areas that are important for decision-making isn’t well understood,” said Wei-Chung Allen Lee, associate professor of neurobio...
If you ask a neuroscientist, they might say, “The chicken crossed the road because the neurons in the chicken’s brain fired and triggered the movement.” Technically speaking, none of these experts are wrong. But nobody is seeing the entire picture either. Each individual mental model is ...
we imagine brain activity as a conversation, neurons have to be connected to each other in order to talk. During the first two weeks after birth, 'no-go' neurons can sense if they are alone and are programmed to die if they cannot find 'go' neurons that are willing to talk to them....

widely recognized at the time of its invention as a major breakthrough in the field. Taking inspiration from the interconnected networks of neurons in the human brain, the architecture introduced an algorithm that enabled computers to fine-tune their decision-making -- in other words, to "learn...
Ahuman braincontains around 100 billion neurons, each of which can communicate with thousands of other neurons via synapses that carry neurotransmitters. "The key concepts here are the nodes and the interconnectivity. And that is quite similar to what we already have in photonic integrated switches....
