Cortical Silent Period Duration Calculator
Actual independently clinically/research identified cortical silent-period boundaries after stated stimulus. Thresholding, task, EMGand component selection external; not an automatically detected silence or inhibition diagnosis.
Description
A cortical silent period requires independently established start and end boundaries.
A cortical silent period requires independently established start and end boundaries.1
Their elapsed duration is separate from identifying silence in the waveform.
When to use Cortical Silent Period Duration Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the assessment or recording protocol, units, instrument version and independently applicable reference or calibration.
How to use Cortical Silent Period Duration Calculator and understand its results
- Establish the assessment or recording protocol, units, instrument version and independently applicable reference or calibration.
- Enter independentlyEstablishedSilentPeriodStartMs, independentlyEstablishedSilentPeriodEndMs, using the field meanings and rules below, then run the tool.
- Read result.observedCorticalSilentPeriodDurationMs. Use the units and sign conventions below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyEstablishedSilentPeriodStartMs | Independently established silent period start ms | number | Required |
| independentlyEstablishedSilentPeriodEndMs | Independently established silent period end ms | number | Required |
Require nonnegative start milliseconds and end≥start. Subtract start from end; zero duration is allowed. Boundaries are supplied independently rather than detected from EMG.
durationMs=endMs−startMs Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result; its nested fields below contain the actual calculation or selected reference | object |
| result.observedCorticalSilentPeriodDurationMs | Observed Cortical Silent Period Duration Ms | number |

}Limitations and assumptions
Actual acquisition, assessment protocol, instrument version and calibration determine applicability. The tool does not examine a person, classify images, administer a questionnaire or choose diagnostic cutoffs.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
