Paragraph 1: The imaging study showed that the two brain regions were active together, but it did not manipulate either region to test causation. Paragraph 2: Participants listened to rhythmic tones while researchers recorded neural activity. Paragraph 3: The authors compared musicians with nonmusicians in a separate exploratory analysis. Paragraph 4: Some scans were excluded because participants moved during the task. The claim to verify is: brain imaging supported correlation rather than a causal conclusion
