The neural basis of predictive pursuit

Area of Science:

• Neuroscience
• Cognitive Science
• Animal Behavior

Background:

• Understanding on-the-fly predictions in nonhuman animals during pursuit is limited.
• Investigating the neural mechanisms underlying predictive behavior is crucial for cognitive neuroscience.

Purpose of the Study:

• To determine if and how nonhuman animals make real-time predictions during pursuit tasks.
• To identify the neural correlates of predictive processing in the brain.
• To elucidate the role of the anterior cingulate cortex in future-oriented cognition.

Main Methods:

• Developed a novel laboratory pursuit task with intelligent prey escape algorithms.
• Trained three macaques on a joystick-controlled pursuit task.
• Utilized a generative model to analyze real-time pursuit trajectories.
• Recorded neural activity in the dorsal anterior cingulate cortex.

Main Results:

• Macaque subjects successfully predicted and aimed for future prey positions, indicating internal prediction generation.
• The generative model confirmed that subjects used prey position, velocity, and acceleration for predictions.
• Neurons in the dorsal anterior cingulate cortex were found to track these predictive variables.
• These neurons exhibited multiplexed representations of prediction variables and explicit future prey positions.

Conclusions:

• The brain can explicitly represent future predictions to guide behavior.
• The dorsal anterior cingulate cortex plays a critical role in enabling future-oriented cognition.
• This study provides clear evidence for predictive processing in nonhuman animals during dynamic tasks.
