Functional brain networks underlying approach-avoidance conflict processing in humans and rats.

Conserved brain network hubs, including hippocampus and insula, underpin approach-avoidance conflict processing in both humans and rats, revealing cross-species similarities.

• Why it matters: Understanding the neural basis of approach-avoidance conflict is crucial for addressing psychiatric conditions involving motivational conflicts, yet the shared network dynamics across species remain unclear.
• What they did: The study conducted a functional network analysis using brain-wide neural activity during learned conflict in humans and rats, focusing on key regions like the hippocampus and insula.
• The result: Findings show that hippocampal regions serve as central hubs and that network topology varies with individual and sex differences, supporting conserved mechanisms for conflict processing.
