But all three labels also elicited some activity in the brain area associated with reward, the ventral striatum, as well as other regions related to desire and feeling connected.»

A mask of a priori selected regions (dorsal and ventral striatum) and those from thalamus and midbrain (including the subthalamic nucleus) was created using the digital anatomical brain atlases provided with the MRIcro software (www.cabiatl.com/mricro/).

These deficits can not be unambiguously ascribed to reduced DA release (because decreases in nondisplaceable binding potential were not blunted) but could reflect a downstream postsynaptic effect that in the ventral striatum (brain reward region) might contribute to marijuana's negative emotionality and addictive behaviors.
