A family with a rare genetic mutation are helping researchers answer important questions about how the human brain is wired. The family, who share an altered copy of the DCC gene, have less connectivity between areas where dopamine neurons originate and their target sites.
A new study reports cocaine increases dopamine levels in the striatum, activating a previously unknown pathway.
Researchers believe the newly understood mechanism could yield insights into more precise future treatments for nerve pain and depression.
