Note

  • In fact, the drug highlights the part of the brain that is responsible for movements and reveals abnormalities.
  • “DAT” stands for “Dopamine active transporter”.
  • Dopamine is a chemical produced by the neurons and responsible for the control of movements. If these neurons die, no dopamine is produced, which causes difficulties in performing automatic movements.
