In this article, Nikhil Swaminathan says that appeared a new study in Nature Neuroscience, which shows that some people whose carry a variant of the ADRA2B gene have a better recall of emotionally than who have not that gene. Some studies of laboratory says the mutation of ADRA2B causes the deletion of three amino acids in the protein that it encodes, what disrupts the behavior of a receptor for the neurotransmitter noradrenaline, which is known to be involved in emotional memory, therefore a receptor modification of this neurotransmitter improves the recall of emotional memories. But, it is necessary doing neuroimaging studies to determine where exactly the effect on the noradrenaline is taking place in the brain.

interesting, but sort of very complicated!!!
check minor mistakes, esp. word order
