DOI: 10.1002/hbm.26088
Abstract: Specific thalamic nuclei are implicated in healthy aging and age‐related neurodegenerative diseases. However, few methods are available for robust automated segmentation of thalamic nuclei. The threefold aims of this study were to validate the use… read more here.

DOI: 10.1002/mrm.28608
Abstract: Thalamic nuclei are largely invisible in conventional MRI due to poor contrast. Thalamus Optimized Multi‐Atlas Segmentation (THOMAS) provides automatic segmentation of 12 thalamic nuclei using white‐matter‐nulled (WMn) Magnetization Prepared Rapid Gradient Echo (MPRAGE) sequence at… read more here.

Opposing collicular influences on the parafascicular (Pf) and posteromedial (POm) thalamic nuclei: relationship to POm-induced inhibition in the substantia nigra pars reticulata (SNR)

DOI: 10.1007/s00429-017-1534-8
Abstract: The superior colliculus activates the zona incerta (ZI), which sends GABAergic projections to the posteromedial (POm) thalamic nucleus. Consistent with this circuit, we previously showed that stimulation of the superior colliculus activates ZI and causes… read more here.
