Naturalistic behavior and self-generated neural activity predictive of self-correction

Area of Science:

• Neuroscience
• Cognitive Science
• Animal Behavior

Background:

• Changing one's mind, or revising decisions, can improve outcomes but its neural underpinnings are not well understood.
• Self-correction is crucial for adaptive behavior, yet the brain mechanisms enabling this process remain largely elusive.

Purpose of the Study:

• To investigate the neural basis of spontaneous decision revision (changes-of-mind) in a controlled experimental setting.
• To explore the role of the hippocampus in representing alternative choices during self-correction.

Main Methods:

• Developed a novel spatial task for rats that induces spontaneous changes-of-mind by conflicting innate biases with task rules.
• Performed neural recordings in the hippocampus while rats engaged in the decision-reversal task.
• Analyzed hippocampal representations to identify patterns associated with decision revision and behavioral outcomes.

Main Results:

• Hippocampal recordings revealed two distinct representational stages during decision revision.
• These stages involved representations shifting from local to distant spatial alternatives as animals reversed course.
• Hippocampal representations predicted the rats' eventual choices and encoded trial parameters.

Conclusions:

• The study uncovers distinct representational phases in the hippocampus during self-correction.
• Hippocampal spatial representations are dynamically updated and linked to behavioral decision revision.
• This work provides novel insights into the neural mechanisms of cognitive flexibility and counterfactual thinking.
