Precise technique tracks dopamine in the brain

March 9, 2017

"MIT researchers have devised a way to measure dopamine in the brain much more precisely than previously possible, which should allow scientists to gain insight into dopamine’s roles in learning, memory, and emotion.

"Dopamine is one of the many neurotransmitters that neurons in the brain use to communicate with each other. Previous systems for measuring these neurotransmitters have been limited in how long they provide accurate readings and how much of the brain they can cover. The new MIT device, an array of tiny carbon electrodes, overcomes both of those obstacles." - MIT News

A new MIT transmitter that measures dopamine overcomes limitations of earlier transmitters, providing accurate readings for longer periods of time and covering more of the brain.
