DGIST (President Lee Kunwoo) Department of Brain Sciences Professor Lee Kwang and his team have discovered a new correlation between neural signaling in the brain and dopamine signaling in the striatum. The human brain requires fast neural signal processing in a short period of less than a second. Dopamine is known to have the strongest effect on brain neural signals, but the research team’s newly developed “optical neural chip-based multiple brain signal monitoring technology” shows that changes in dopamine signals within the physiological range do not affect brain neural signal processing.

Dopamine is a chemical neuromodulator that plays an essential role in learning, movement, motivation, and decision-making. It has been linked to a number of diseases, including Parkinson’s disease, addiction,...
