SEATTLE, WASH. — From a tiny sample of tissue no larger than a grain of sand, scientists have come within reach of a goal once thought unattainable: building a complete functional wiring diagram of a ...

Your brain ventricles are four fluid-filled chambers that produce cerebrospinal fluid. This fluid helps nourish your brain and protect it from injury. It would be easy to argue that your brain is the ...

The first wiring diagram of every neuron in an adult brain and the 50 million connections between them has been produced for a fruit fly. The diagram of all 139,255 neurons in the adult fly brain is ...

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior ...

What unique processes conspire to create a healthy, functional human brain? How can we be so genetically similar to, say, chimpanzees, and yet be light-years more sophisticated cognitively and ...

Researchers in Japan built a miniature human brain circuit using fused stem-cell–derived organoids, allowing them to watch the thalamus and cortex interact in real time. They found that the thalamus ...

Brain volume and function are altered in individuals with opioid use disorder, a new Yale study finds. Using magnetic resonance imaging (MRI) and functional MRI (fMRI), researchers observed the ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

New research shows gut bacteria can directly influence how the brain develops and functions. When scientists transferred microbes from different primates into mice, the animals’ brains began to ...
