It takes a huge amount of energy for human brains to grow to their current large size and be maintained over time. Our early ...

Brain tissue is among the most energetically costly in the body, and as a result, larger-brained mammals require more energy to support brain growth and maintenance. Exactly which biological changes ...

A new laboratory study in mice suggests that primates like humans evolved large brains with a helping hand from microbes that ...

searching and obtaining food or provisions. Primates are used in brain studies because of their close biological and ...

A new study suggests that gut microbes played a key role in the evolution of larger brains in primates by influencing energy ...

Brain tissue ... break down food and produce energy. In a controlled lab experiment, researchers implanted microbes from two large-brain primate species (human and squirrel monkey), and one ...

Functional magnetic resonance imaging (fMRI) has become an essential tool for studying human brain function. Here we describe the application of this technique to anesthetized monkeys. We present ...
