The distinct aging rates of neural progenitor cells and Wnt signaling dictate mammalian cortical layer proportions.

The outer regions of the brain, the cortex, have specific layers of different cells—neurons—that are similarly ordered among all mammals, from tiny mouse brains to huge elephant brains. However, the ...

Perhaps our most defining characteristic as a species, the six-layered human cortex, hosts billions of neural connections that bestow Homo sapiens with higher-order thinking. But how does this ...

Researchers have discovered that parts of the human brain age more slowly than previously thought—particularly in the region that processes touch. By using ultra-high-resolution brain scans, they ...

Researchers from The University of Osaka have found that the rat brain differs from other mammals in the proportion of upper ...

A layer deep in the cerebral cortex, which is the innermost layer of the mammalian brain, has recently been found to play a role in the regulation of brain states associated with wakefulness and ...

DNA damage from inflammation outpaces the cells’ ability to self-repair. The finding, in human brain cells and mice, could ...

Even in the primary visual cortex, a brain region named for its specialized role in processing basic features of what the eyes see, not every neuron ends up answering the call to process properties of ...
