Deep brain stimulation for movement disorder treatment: Exploring frequency-dependent efficacy in a computational network model [PDF]

open access: yesarXiv, 2020
A large scale computational model of the basal ganglia (BG) network is proposed to describes movement disorder including deep brain stimulation (DBS). The model of this complex network considers four areas of the basal ganglia network: the subthalamic nucleus (STN) as target area of DBS, globus pallidus, both pars externa and pars interna (GPe-GPi ...

A Multiple Kernel Learning Approach for Human Behavioral Task Classification using STN-LFP Signal [PDF]

open access: yes, 2016
Deep Brain Stimulation (DBS) has gained increasing attention as an effective method to mitigate Parkinsons disease (PD) disorders. Existing DBS systems are open-loop such that the system parameters are not adjusted automatically based on patients behavior. Classification of human behavior is an important step in the design of the next generation of DBS

Physical therapy and deep brain stimulation in Parkinson’s Disease: Protocol for a pilot randomized controlled trial [PDF]

open access: yes, 2018

Local vs. volume conductance activity of field potentials in the human subthalamic nucleus.

open access: yesJournal of Neurophysiology, 2017
Subthalamic nucleus field potentials have attracted growing research and clinical interest over the last few decades. However, it is unclear whether subthalamic field potentials represent locally generated neuronal subthreshold activity or volume ...

Dyskinesias and the subthalamic nucleus.

open access: yesAnnals of neurology, 2000
Severe dyskinesias or ballism can occur following hemorrhagic events in the subthalamic nucleus (STN), and it has recently been established that the STN plays a major role in the pathophysiology of the motor dysfunction of Parkinson's disease (PD) and that STN inhibition improves parkinsonian dysfunction.

Striatal cholinergic interneurons generate beta and gamma oscillations in the corticostriatal circuit and produce motor deficits [PDF]

open access: yes, 2016
Cortico-basal ganglia-thalamic (CBT) neural circuits are critical modulators of cognitive and motor function. When compromised, these circuits contribute to neurological and psychiatric disorders, such as Parkinson's disease (PD).

Magnetic resonance imaging of the subthalamic nucleus for deep brain stimulation.

open access: yesJournal of Neurosurgery, 2016
The subthalamic nucleus (STN) is one of the most important stereotactic targets in neurosurgery, and its accurate imaging is crucial. With improving MRI sequences there is impetus for direct targeting of the STN.

Acute hemiballismus in the absence of subthalamic nucleus lesion

open access: yesMGM Journal of Medical Sciences, 2020
A 68-year-old male, known hypertensive on irregular medication presented with sudden onset of involuntary movements of the left upper limb, in the form of severely violent, arrhythmic, and flinging large amplitude movements for 2 days, suggestive of ...

Continuous Dice Coefficient: a Method for Evaluating Probabilistic Segmentations [PDF]

open access: yesarXiv, 2019
Objective: Overlapping measures are often utilized to quantify the similarity between two binary regions. However, modern segmentation algorithms output a probability or confidence map with continuous values in the zero-to-one interval. Moreover, these binary overlapping measures are biased to structure size.

Totally Implantable Bidirectional Neural Prostheses: A Flexible Platform for Innovation in Neuromodulation. [PDF]

open access: yes, 2018
Implantable neural prostheses are in widespread use for treating a variety of brain disorders. Until recently, most implantable brain devices have been unidirectional, either delivering neurostimulation without brain sensing, or sensing brain activity to
