Abstract
In the recordings of middle latency responses of auditory evoked magnetic fields in 4 male subjects, we observed distinct components at 11, 19 and 33 ms after click stimulus. Equivalent current dipole sources of these components were located in the supratemporal auditory cortex, where the earliest component source was found at the most medial site.
AI evidence extraction
Structured fields below were generated from the paper’s abstract and metadata to make the evidence easier to inspect. Automated extraction may be incomplete or incorrect; verify important details against the original paper.
Main findings
In 4 male subjects, distinct middle-latency components of the auditory evoked magnetic field were observed at 11, 19, and 33 ms after a click stimulus. Equivalent current dipole sources for these components were localized to the supratemporal auditory cortex, with the earliest component located most medially.
Outcomes measured
- Middle latency responses of auditory evoked magnetic fields (components at 11, 19, 33 ms after click stimulus)
- Estimated cortical source locations (equivalent current dipoles) in supratemporal auditory cortex
Limitations
- Very small sample size (n=4)
- Only male subjects included
- No EMF exposure characterization (frequency, intensity, duration) described in abstract
