Potential mechanisms for imperfect synchronization in parkinsonian basal ganglia [PDF]
Neural activity in the brain of parkinsonian patients is characterized by the intermittently synchronized oscillatory dynamics. This imperfect synchronization, observed in the beta frequency band, is believed to be related to the hypokinetic motor ...

Anatomy and Connectivity of the Subthalamic Nucleus in Humans and Non-human Primates
The Subthalamic Nucleus (STh) is an oval-shaped diencephalic structure located ventrally to the thalamus, playing a fundamental role in the circuitry of the basal ganglia.

Subthalamic Nucleus Deep Brain Stimulation Modulates 2 Distinct Neurocircuits
Current understanding of the neuromodulatory effects of deep brain stimulation (DBS) on large‐scale brain networks remains elusive, largely due to the lack of techniques that can reveal DBS‐induced activity at the whole‐brain level.

Imaging of the human subthalamic nucleus
The human subthalamic nucleus (STN) is a small lens shaped iron rich nucleus, which has gained substantial interest as a target for deep brain stimulation surgery for a variety of movement disorders. The internal anatomy of the human STN has not been fully elucidated, and an intensive debate, discussing the level of overlap between putative limbic ...

Brain tissue properties differentiate between motor and limbic basal ganglia circuits [PDF]
Despite advances in understanding basic organizational principles of the human basal ganglia, accurate in vivo assessment of their anatomical properties is essential to improve early diagnosis in disorders with corticosubcortical pathology and optimize ...

A role for the subthalamic nucleus in aversive learning
The subthalamic nucleus (STN) is critical for behavioral control; its dysregulation consequently correlated with neurological and neuropsychiatric disorders, including Parkinson's disease. Deep brain stimulation (DBS) targeting the STN successfully alleviates parkinsonian motor symptoms. However, low mood and depression are affective side effects.

Development of a novel gripping test for the evaluation of the finger fine motor ability in MPTP-treated monkeys [PDF]
Assessing the finger fine motor ability is extremely important. However, conventional behavioral tests in monkeys are complicated and costly. We attempted to develop a new task to assess the precise finger grip in Parkinson's disease monkeys based on the

The subcortical cocktail problem; mixed signals from the subthalamic nucleus and substantia nigra.
The subthalamic nucleus and the directly adjacent substantia nigra are small and important structures in the basal ganglia. Functional magnetic resonance imaging studies have shown that the subthalamic nucleus and substantia nigra are selectively ...

Patients with psychiatric symptoms, such as depression, anxiety, and visual hallucinations, may be at increased risk for adverse effects following deep brain stimulation of the subthalamic nucleus for Parkinson’s disease, but there have been relatively ...
