A recent study conducted in Tianjin, China explored the effects of exposure to different frequencies of electromagnetic fields on long-term potentiation (LTP) in the hippocampal CA1 region of rats. LTP is closely related to learning and memory. The researchers found that calcium ions (Ca2+) play a key role in the modulation of LTP by magnetic fields of different frequencies. Low levels of intracellular calcium concentration intensified the inhibition of low-frequency magnetic fields on LTP, while high levels enhanced the promotion effect of high-frequency magnetic fields on LTP. These findings may contribute to a better understanding of the relationship between magnetic fields and synaptic plasticity, and could have implications for the treatment of neurological diseases related to LTP injury or learning and memory deficits.
