A study into the emotions of psychopaths has won Medical Research Council support. Researchers at University College, London, will try to understand why psychopaths are aggressive and feel no remorse. The emotions of empathy and fear and their basis in the brain will be investigated as part of the three-year Pounds 196,000 study. The MRC has also given Pounds 3.4 million to five other studies including including ones looking at diabetes, digestion and breast cancer.
