Direct link between GABA activation and dopamine suppression
Using sophisticated electrophysiology and cell chemistry measures, the study team could monitor the activity of the GABA and dopamine neurons. They found a direct link between GABA activation and dopamine suppression. "So basically, it appears that these GABA neurons located in the VTA are just microns away from dopamine and are negative regulators of dopamine function," Stuber proposes. "When they become active, their basic job is to suppress dopamine release. A dysfunction in these GABA neurons might potentially underlie different aspects of neuropsychiatric illness, such as depression. Thus, we could think of them as a new physiological target for various aspects of neuropsychiatric diseases."
