Poppy-cocked

     Experiments on neurons show the ability to control the dopamine response.  This seems quite the breakthrough seeing that the dopamine receptors themselves were only discovered in 1958 by Arvid carlsson.

     "GABA neurons located in the VTA are just microns away from dopamine and are negative regulators of dopamine funtion," 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."
