Everyone knows what it's like to itch,

and the sensation can drive you mad.

Or if you're Yang Gao Sun of the Chinese Academy of Sciences,

it can drive you to explore how the brain tells you it's time to scratch.

Our study is aiming to understand the brain mechanism that promote the each-scratching cycle. Itching can be caused by a number of irritants,

from allergic reactions and abrasive textures to bug bites, skin conditions, infections or drugs.

The usual solution is to simply scratch.

But this cycle of itching and scratching,

if it continues unabated, can actually damage tissue, like if you scratch yourself raw. And Sun

notes that... Effective treatment for chronic age is still lacking. This is largely due to our

limited knowledge about the neuromechanism of age. Over the past 10 years, scientists have learned a lot about how the itch signal is carried

from the skin to the spinal cord.

In contrast, we know very little about how each information is processed in the brain, and

how the brain can dynamically modulate the processing of each.

Sun and his colleagues focus their attention on the peri-aqueductal gray,
