• To highlight circuit-based methodologies applied to the superior colliculus.
• To integrate knowledge across species and methodologies.

Main Methods:

• Review of existing literature on the superior colliculus.
• Analysis of studies in monkeys and birds.
• Incorporation of research using transgenic mouse models and circuit-based approaches.

Main Results:

• The superior colliculus plays a critical role in reorienting organisms toward salient stimuli.
• Recent research expands its known functions to include attention and decision-making.
• Circuit-level investigations in mice are providing detailed insights.

Conclusions:

• The superior colliculus is fundamental to complex behaviors, including attention and decision-making.
• New tools and extensive data offer a unique opportunity to elucidate its neural underpinnings.
