Abstract in brief

People with Internet addiction have fewer dopamine D2 receptors in certain brain areas, specifically in parts of the striatum like the dorsal caudate and right putamen.
The study used a special imaging technique called PET with a radiolabeled ligand called Craclopride to measure receptor levels in the brain.
This research supports the idea that neurobiological changes, such as reduced dopamine receptor availability, are linked to Internet addiction, helping us understand its underlying brain mechanisms.]
