Scientists who observed the accelerated growth of mouse neurons after the rodents were exposed to brief, low-dose radiation from terahertz waves say their findings have implications for future communication devices.
The discovery could help evaluate the safety of new communication technology and also develop therapies to treat brain diseases, according to the researchers. Their results also suggested “terahertz waves of certain frequencies and energies can be developed as a novel neuromodulation technology” to treat or intervene in diseases such as neurodevelopmental disorders.
According to a study by researchers at the Russian Academy of Sciences in 2009, exposure to strong terahertz radiation for several hours a day, with power reaching a few watts, could increase temperature in brain cells, disturb their development and cause dehydration that reduces cell size and other damage.
Terahertz waves “can directly couple with proteins and effectively cause them to resonate in a non-linear manner,” Li’s team said in the paper. They said more investigation was needed to understand the protein changes induced by different exposure intensities.
