Changes in the content of dopamine, serotonin, their precursors and derivatives in the prefrontal cortex of young male rats under chronic exposure to a low-intensity electromagnetic field

This study adds to growing evidence that Wi-Fi radiation affects developing brains at the neurochemical level. The researchers found disrupted dopamine and serotonin systems in the prefrontal cortex, the brain region responsible for executive function, decision-making, and social behavior. What makes this particularly concerning is the exposure level: 0.46 µW/cm² is well within typical home Wi-Fi exposure ranges, yet it was enough to alter fundamental brain chemistry during critical developmental windows.

The science demonstrates that even low-level chronic exposure can have measurable biological effects on neurotransmitter systems that govern behavior and cognition. The authors explicitly call for reassessing current safety standards, acknowledging that existing limits may not adequately protect developing nervous systems. This research reinforces why precautionary approaches matter most for children, whose brains are actively forming the neural networks that will serve them throughout life.
