brain imaging

New scientific discoveries and research can make people understand many things that are unknown before and provide people better and more comfortable life. However, at the same time, they bring us some negative impacts. For example, the development of functional magnetic resonance imaging (fMRI) can help detect and locate brain activity when people thinking and predict the brain activation patterns and thus contributes a lot in the field of treating mental diseases, but also may raise a series of ethical problems, such as abuses and testing of children. Therefore, researchers should predict and minimize potential unethical abuses of their works.Firstly, access is a significant issue. Researchers should well keep all the data related to the research, ranging from the data and experiment results to the final work. As under some circumstances, a few unethical researchers and organizations may embezzle the unfinished works to obtain profits or reputation from them. However, they may misuse the information and cause some problems. For example, the manufacturing of nuclear weapons and other threatening weapons should be the top secret. All the things related to the manufacturing process and the material needed must be taken very good care of, in case of misuse by terrorists. Thus, the access to the database should be secured.Moreover, in order to prevent the potential unethical abuses happening, researchers have to predict the potential abuses caused by the research in advance and think of ways to overcome them. Therefore, before the research done, researchers should minimize the possible troubles and then prevent wicked people making use of it. Also, rules and regulations must to be made in dealing with the unethical problems. In conclusion, the development of science and technology raises some ethical issues. To prevent and minimize the unethical abuses of the research works, researchers have to be responsible for the accuracy and security of their works and be aware of the potential unethical issues.
