| Subject | Target | Right | Left |
|---|---|---|---|
| SCA2 | Vim | X 11.2, Y –6.4, Z –1.9 | |
| FXTAS | Vim | X –12.9, Y –9.9, Z –0.79 | |
| VOA | X –13.4, Y –7.89, Z –1.7 | ||
| Ataxia NOS | Vim | X –13, Y –6.91, Z –3.5 | |
| SCA17 | GPi | X 18, Y 1.8, Z –4.1 | X –20.5, Y 1.8, Z –6.6 |
| SETX | GPi | X 19.5, Y 0.71, Z –4.57 | X –22, Y –0.3, Z –4.2 |
Lead locations were derived from computed tomography–magnetic resonance imaging fusion.
Measurements were made in reference to the mid-commissural point: Y, anteroposterior; X, mediolateral; Z, axial; Vim, Thalamic Ventralis Intermedius Nucleus; GPi, Posteroventral Globus Pallidus Internus; VOA–VOP, Thalamic Ventralis Oralis Anterior and Ventralis Oralis Posterior.
Ataxia NOS, Ataxia Not Otherwise Specified; FXTAS, Fragile X Ataxia Syndrome; SCA2, Spinocerebellar Ataxia Type 2; SCA17, Spinocerebellar Ataxia Type 17; SETX, Senataxin Mutation-associated Ataxia.
