Pavlovian Bias Data from TUS Study of 29 Human Participants

Data from a 2026 study using transcranial ultrasonic stimulation (TUS) on 29 healthy participants to investigate the neural origins of Pavlovian biases. The dataset, shared by Nomiki Koutsoumpari on figshare, contains results from 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 effect of brain stimulation on learning bias based on TUS-aIns interference.
• Analyzing the causal role of dACC in cue-dependent perseveration based on TUS-dACC results.
• Comparing neural mechanisms of response, learning, and perseveration biases from within-subject experimental data.
• Testing computational models of decision-making against empirical brain stimulation data.

Strengths

• Dataset is based on a within-subject, counter-balanced experimental design with 29 participants.
• Results are derived from computational modeling of behavioral data.
• Data is shared under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 21.2 KB, indicating limited scope.
