How the Brain Turns an Itch Into a Scratch

An indirect neural pathway communicates the sensation of itchiness to the brain, and the discovery means researchers believe itch-suppressing therapies might be possible.

Itch-mediating spinal neurons, which express the gastrin-releasing peptide receptor, are disynaptically connected to the parabrachial nucleus via glutamatergic spinal projection neurons. | Sun Yangang's lab
