Effect of cell-phone radiation exposure on cognitive function in humans

Several papers reporting on cognitive function and exposure to cell-phone RF fields have appeared in scientific journals. Human subjects exposed to cell-phone fields showed faster responses in simple reaction time and in choice reaction time. In addition, some investigations have found exposure to cell-phone fields has a facilitating effect on tasks that require attention and manipulation of information in working memory. Also, the same group failed to confirm their earlier findings when they repeated their experiments. On the other hand, as a follow-up, different research groups examined the relationship between the reported facilitating effect and cell-phone exposure. Their results indicated that cognitive process, such as attentional function, are differentially enhanced after exposure to the RF fields emitted by cell phones.
