Learning and memory endpoints at 7.5 kHz

The reported finding

The 120-microtesla group showed impaired task acquisition and passive-avoidance retention, with elevated hippocampal TNF-alpha expression.

Reading it carefully

Equipment problems required a separate high-exposure cohort. Many other endpoints were unchanged. The high field exceeded the occupational reference level cited by the authors.

Inside the study

Exposure conditions
7.5 kHz magnetic field; sham, 12 or 120 microtesla; continuous exposure for five weeks.
Design & controls
70 male mice: 30 sham and 20 per exposed group.
The protection question raised
Do the memory and inflammatory findings persist with concurrent comparison groups? The separate high-exposure cohort limits inference, and intermediate-frequency conditions cannot be transferred directly to public RF exposures.
