  • Traditionally linked to reward processing, dopamine and serotonin might have far greater roles in the human nervous system than previously known.
  • For the first time, moment-to-moment activity of dopamine and serotonin transmitter systems was measured, indicating that they’re involved in perception and cognition.
  • Using an electrochemical method, with a small carbon fiber microelectrode, researchers recorded neurotransmitter changes in five patients during brain surgery.
  • Many psychiatric and neurological disorders change how we absorb information, interpret it, and make decisions - dopamine and serotonin are key suspects.
