Neurons

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

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.

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

New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.

A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.

A technique based on genetic bar codes can easily map the connections of individual brain cells in unprecedented numbers. Unexpected complexity in the visual system is only the first secret it has revealed.

Using a brain-computer interface, scientists are beginning to learn why learning is hard.
