Mapping the Amygdala Leads to New Hope For Cocaine Addiction

Researchers crafted a detailed atlas of the amygdala, revealing new insights into emotional responses and potential treatments for cocaine addiction. A cell-by-cell study of the amygdala, a brain structure vital in controlling emotional reactions, has exposed previously unobserved links between addiction behaviors and genes related to energy metabolism, suggesting energy management in neurons could influence addiction-like actions.

How Gut Bacteria Influence the Effects of Cocaine in Mice

Cocaine use supports the growth of γ-proteobacteria, a common gut bacteria that consume glycine. As glycine levels become depleted mouse models exhibit a higher response to cocaine with abnormal behaviors including increased drug-induced locomotion and drug-seeking behaviors.

Surprising effects of oxytocin on cocaine addiction

In men with a history of childhood trauma, oxytocin reduced the activity within the amygdala and cravings for cocaine. Women who were addicted to cocaine and had experienced childhood trauma showed an increase in amygdala activity following exposure to oxytocin.

Chronic cocaine use modifies gene expression

Chronic cocaine use alters the epigenetic profile of the FosB gene in the hippocampus. These alterations are required for cocaine-dependent gene expression and cocaine environment associations. Modification of hippocampal FosB results in a condition critical for cocaine-related learning.
