Dystonia is a movement disorder in which excessive muscle contractions cause abnormal movement. It is classified according to its clinical manifestations (onset, distribution, temporal and associated features) and etiology (pathology and inheritance). Deep brain stimulation (DBS) is a surgical procedure used to treat medically intractable dystonia. In this study, we aim to share our experience with general anesthesia in systemic idiopathic dystonia that was not controlled by drugs, along with a literature review. A 21-year-old man with generalized idiopathic dystonia and developmental delay was scheduled to undergo deep brain stimulator implantation under general anesthesia. Intubation of the endotracheal tube and fixation of the stereotactic frame were performed in the intensive care unit (ICU) under sedation and neuromuscular blockade before arrival at the operating room. Total intravenous anesthesia was administered. After an uneventful surgery, the patient was discharged to the ICU with an endotracheal tube. As dystonia has a wide clinical spectrum and DBS requires special anesthetic considerations, anesthesiologists should adopt proper anesthetic depth and neuromuscular blockade according to each patient's condition.

Emerging Deep Brain Stimulation Targets in the Cerebellum for Tremor.

Deep brain stimulation (DBS) for essential tremor is remarkably effective, leading to over 80% reduction in standardized tremor ratings. However, for certain types of tremor, such as those accompanied by ataxia or dystonia, conventional DBS targets have shown poor efficacy. Various rationales for using cerebellar DBS stimulation to treat tremor have been advanced, but the varied approaches leave many questions unanswered: which anatomic target, stimulation settings, and indications seem most promising for this emerging approach.

Objective: Disorders of arousal (DoA) are characterized by an intermediate state between wakefulness and deep sleep, leading to incomplete awakenings from NREM sleep. Multimodal studies have shown subtle neurophysiologic alterations even during wakefulness in DoA. The aim of this study was to explore the brain functional connectivity in DoA and the metabolic profile of the anterior and posterior cingulate cortex, given its pivotal role in cognitive and emotional processing.

A major challenge in NHP optogenetics is delivering light to sufficiently large volumes of deep neural tissue with high spatiotemporal precision, without simultaneously affecting superficial tissue. To overcome these limitations, we recently developed and tested in NHP cortex, the Utah Optrode Array (UOA).

Introduction: Sleep deprivation (SD) significantly disrupts the homeostasis of the cardiac-brain axis, yet the neuromodulation effects of deep magnetic stimulation (DMS), a non-invasive and safe method, remain poorly understood.
Methods: Sixty healthy adult males were recruited for a 36-h SD study, they were assigned to the DMS group or the control group according to their individual willing. All individuals underwent heart sound measurements and functional magnetic resonance imaging scans at the experiment's onset and terminal points.

Introduction: The study of attention has been pivotal in advancing our comprehension of cognition. The goal of this study is to investigate which EEG data representations or features are most closely linked to attention, and to what extent they can handle the cross-subject variability.
Methods: We explore the features obtained from the univariate time series from a single EEG channel, such as time domain features and recurrence plots, as well as representations obtained directly from the multivariate time series, such as global field power or functional brain networks.
