A recent study published in the International Journal of Developmental Neuroscience found that rats exposed to wireless radiation in utero experienced impacts to their hippocampus, a region of the brain critical for learning and memory.
In short:
- The neurons of exposed rats became darkly stained and shrunken, indicating cellular damage.
- Exposed rats also had higher levels of proteins associated with cell death in regions of the hippocampus that play an important role in memory formation, spatial navigation, and cognitive flexibility.
- These effects were found in rats exposed during a critical stage of pregnancy when neurogenesis - the formation of new neurons - takes place, suggesting that wireless exposure may disrupt normal brain development
“This could potentially lead to long-term deficits in cognitive abilities, raising concerns about the potential impact of EMF exposure on brain health, especially during early development.”
