MODEL RELEASED. Dopamine research. Study into the abundance of dopamine D2 receptors in the brain. The darker speckles on the brain on the computer image indicate a larger amount of receptors. Dopamine is an abundant brain chemical which helps control muscle movements and thought processes. Here,the brain was exposed to a radioactive dopamine analogue. This bound to the receptors,and the radioactivity caused a darkening of the photographic film it was held against. Dopamine research is largely aimed at diseases in which there are abnormal levels of the chemical,such as Parkinson's disease and schizophrenia | |
