brains

Deep neural networks, often criticized as “black boxes,” are helping neuroscientists understand the organization of living brains.

New research links serotonin and dopamine not just to addiction and depression, but to the ability to control genes.

Research hints that the energy-generating organelles of cells may play a surprisingly pivotal role in mediating anxiety and depression.

The nervous systems of foraging and predatory animals may prompt them to move along a special kind of random path called a Lévy walk to find food efficiently when no clues are available.

Neuroscientists could use brain waves to spur immune cells into action against the disease — but the process is almost too fantastic to believe.

How does experience alter our perceptions? This adapted book excerpt from We Know It When We See It describes how the brain’s visual system rewires itself to make the best use of its neural resources.

Faced with a decision, the brain weighs its options by bundling them into rapidly alternating cycles of brain waves.

Collaborations in progress between ethicists and biologists seek to head off challenges raised by lab-grown “organoids” as they become increasingly similar to human brain tissue.

The dendritic arms of some human neurons can perform logic operations that once seemed to require whole neural networks.
