Caveats
- The Mendeley dataset contains Parkinson's disease patient trials with DBS off/on labels, not a broad healthy-volunteer reference sample.
- The source `cdiff` field is left-minus-right clicks at response. The atlas canonical axis flips this to right-minus-left for cross-clicks consistency.
- Click-time kernels use click events up to the response time. The source also includes the pre-scheduled trial duration and clicks after response in task_variables for auditability.
- This is a descriptive choice-triggered evidence kernel, not a full accumulation-model fit.
- Click times are normalized by each trial's stimulus duration, so bins compare relative rather than absolute stimulus time.
- Only left and right response trials with click times and stimulus duration are used.
