PARIS - Researchers said on Monday they had mapped the network in the brain linked to addiction by studying long-time smokers who abruptly quit after suffering brain lesions.

They hope the research will give future treatments a target to aim for in the fight against addiction to a range of substances.

While the lesions of those who stopped smoking were not located in one specific region of the brain, they mapped them to a number of areas - what they called the"addiction remission network". Previous research has shown that lesions affecting the insula relieve addiction. But it failed to take into account other parts of the brain identified in the new study.

Juho Joutsa, a neurologist at Finland's University of Turku and the study's author, told AFP"the identified network provides a testable target for treatment efforts"."Some of the hubs of the network were located in the cortex, which could be targeted even with non-invasive neuromodulation techniques," he added.
