Technical Comparison of Treatment Efficiency of Magnetic Resonance-Guided Focused Ultrasound Thalamotomy and Pallidotomy in Skull Density Ratio-Matched Patient Cohorts [PDF]
Frontiers in Neurology, 2022 ObjectiveMR-guided focused ultrasound (MRgFUS) is increasingly being used to treat patients with essential tremor (ET) and Parkinson's disease (PD) with thalamotomy and pallidotomy, respectively.

Altered Activation in Cerebellum Contralateral to Unilateral Thalamotomy May Mediate Tremor Suppression in Parkinson's Disease: A Short-Term Regional Homogeneity fMRI Study. [PDF]
PLoS ONE, 2016 BACKGROUND:Ventral intermediate nucleus thalamotomy is an effective treatment for Parkinson's disease tremor. However, its mechanism is still unclear. PURPOSE:We used resting-state fMRI to investigate short-term ReHo changes after unilateral thalamotomy ...

Stereotaxic Thalamotomy for Pain Relief
The Tohoku Journal of Experimental Medicine, 1968 As a preliminary experimental study, the activity of single units of the thalamic pulvinar nucleus was studied in cats, and it was found that some of the pulvinar neurons responded to nociceptive stimuli such as pinpricks with a needle and pinching with toothed forceps.

Novel Objective Tool to Assess Tremor Reveals Unilateral Focused Ultrasound Improves Tremor Bilaterally [PDF]
Neurology and TherapyBackground Tremor in essential tremor and in tremor-dominant Parkinson’s disease is assessed by subjective observations in patients undergoing focused ultrasound thalamotomy, a minimally invasive procedure intended to alleviate tremor in these patients ...

Levodopa-induced dyskinesia and thalamotomy. [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1984 Levodopa-induced dyskinesia of the limbs in thirteen cases of Parkinsonism, which was choreic, ballistic or dystonic in type, was alleviated almost completely by stereotaxic surgery using a microelectrode technique for the ventralis oralis anterior and posterior nuclei of the thalamus, but much less by the ventralis intermedius nucleus.

New technique for direct targeting of the ventral intermediate nucleus using magnetic resonance-guided focused ultrasound [PDF]
Frontiers in RadiologyBackgroundAccurate targeting and lesion placement are critical in treating movement disorders with magnetic resonance-guided focused ultrasound (MRgFUS). Indirect atlas-based targeting often lacks precision. Direct anatomical targeting with 3T MRI offers

Profiling functional networks identify activation of corticostriatal connectivity in ET patients after MRgFUS thalamotomy [PDF]
NeuroImage: ClinicalBackground: MR-guided focused ultrasound (MRgFUS) thalamotomy is a novel and effective treatment for medication-refractory tremor in essential tremor (ET), but how the brain responds to this deliberate lesion is not clear.
