Pavlovian Bias Data from Transcranial Ultrasonic Stimulation Study

Source data from a study investigating the neural origins of Pavlovian biases using transcranial ultrasonic stimulation (TUS). The dataset includes results from 29 healthy participants in a within-subject, counter-balanced design across three sessions (sham, TUS-dACC, TUS-aIns). Computational modeling revealed distinct roles for the dorsal anterior cingulate cortex and anterior insula in learning and perseveration biases.

Use Cases

• Modeling the distinct roles of dACC and aIns in Pavlovian biases based on the described TUS interference results.
• Analyzing the effect of non-invasive brain stimulation on learning bias and perseveration bias as described in the study.
• Investigating the functional differentiation within the 'reset network' for cue-dependent persistence versus outcome inference.
• Comparing computational model parameters for response, learning, and perseveration biases across stimulation conditions.

Strengths

• Data originates from a controlled within-subject experimental design with 29 participants.
• Includes results from three distinct intervention sessions (sham, TUS-dACC, TUS-aIns) allowing for direct comparison.
• Findings are supported by computational modeling, as stated in the description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 20.8 KB, indicating limited scope.
