• Analysis of neural data from multiple brain regions during a cognitive task.
• Focus on methods applicable to studying single-trial neural dynamics and behavioral control.

Main Results:

• Simultaneous recordings enable the study of how multi-regional interactions coordinate neural representations.
• Understanding these interactions is critical for deciphering single-trial behavioral control.
• The reviewed methods provide a framework for investigating brain-wide neural dynamics.

Conclusions:

• Analyzing neural activity across multiple brain areas is essential for a comprehensive understanding of cognition.
• Advanced recording technologies facilitate the study of complex neural coordination.
