Auditory Cortex MEG Responses to Masked Tone Streams with Varying Inter-Stimulus Intervals

Magnetoencephalography recordings from human auditory cortex during perception of isochronous tone streams under multi-tone masking. The data probe the amplitude of awareness-related negativity (ARN) and N1 responses across inter-stimulus intervals of 500, 850, and 1200 ms. The dataset was contributed by Clara Raudonat via heiDATA Harvested Dataverse and was last updated on 2026-01-18.

Use Cases

• Modeling the relationship between inter-stimulus interval and awareness-related negativity amplitude based on the described experimental paradigm.
• Comparing neural responses to attended versus unattended auditory streams using the negative difference waveform (Nd) data.
• Investigating the neural formation of auditory streams under informational masking conditions described in the experiments.

Strengths

• Data includes recordings from magnetoencephalography, a high-temporal-resolution neuroimaging technique.
• Experimental design includes three specific inter-stimulus intervals (500, 850, 1200 ms) and both masked and unmasked conditions.
• Last updated date is explicitly provided as 2026-01-18 08:10:13.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats and data size are unspecified, complicating download planning.
