This bar graph shows that structures in the brain's striatal region are enlarged in methamphetamine abusers. Average volumes of the globus pallidus and putamen structures in the brain's striatal region are larger in men and women with a history of methamphetamine abuse than in men and women with no exposure to the drug. The data for each category is as follows:
Comparison subjects:
- Right Putamen Level for men : approximately 5.2 ml
- Left Putamen Level for men : approximately 5.8 ml
- Right Putamen Level for women : approximately 5.2 ml
- Left Putamen Level for women : approximately 5.4 ml
- Right globus pallidus Level for men : approximately 1.7 ml
- Left globus pallidus for men : approximately 1.75 ml
- Right globus pallidus for women : approximately 1.7 ml
- Left globus pallidus for women : approximately 1.6 ml
Meth subjects:
- Right Putamen Level for men : approximately 6.4 ml
- Left Putamen Level for men : approximately 6.6 ml
- Right Putamen Level for women : approximately 6.0 ml
- Left Putamen Level for women : approximately 6.3 ml
- Right globus pallidus Level for men : approximately 1.9 ml
- Left globus pallidus for men : approximately 1.85 ml
- Right globus pallidus for women : approximately 1.8 ml
