Voluntary movement, motivation, and reinforcement learning depend on the activity of ventral midbrain neurons, which extend axons to release dopamine (DA) in the striatum. These neurons exhibit two patterns of action potential activity: low-frequency tonic activity that is intrinsically generated and superimposed high-frequency phasic bursts that are driven by synaptic inputs. acute striatal brain preparations are widely employed to study the regulation of evoked DA release but exhibit very different DA release kinetics than recordings.

Study Objectives: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) may improve sleep dysfunction, a common non-motor symptom of Parkinson disease (PD). Improvement in motor symptoms correlates with DBS-suppressed local field potential (LFP) activity, particularly in the beta frequency (13 - 30 Hz). Although well-characterized in the short term, little is known about the innate progression of these oscillations across the sleep-wake cycle.

Pityriasis rosea (PR) is a prevalent dermatological condition characterized by a distinctive herald patch, followed by secondary eruptions, often forming a "Christmas tree" pattern on the trunk. Despite its recognizable clinical presentation, the etiology of PR remains uncertain, with hypotheses pointing to both infectious and noninfectious origins. Human herpesviruses (HHV) 6 and 7 have been implicated, with evidence suggesting viral reactivation as a potential trigger.

The COVID-19 pandemic led to significant shifts in societal norms and individual behaviors, including changes in physical activity levels. This study examines the relationship between socioeconomic and sociodemographic factors and changes in physical activity levels during the pandemic compared to pre-pandemic levels among adult Arkansans. Survey data were collected from 1,205 adult Arkansans in July and August 2020, capturing socioeconomic and sociodemographic characteristics and information on physical activity changes since the onset of the pandemic.

Unlabelled: Klinefelter syndrome (KS) is the most common sex chromosomal aneuploidy in males (47,XXY karyotype in 80-90% of cases), primarily characterized by hypergonadotropic hypogonadism and infertility. It encompasses a broad phenotypic spectrum, leading to variability in neurocognitive and psychosocial outcomes among affected individuals. Despite the recognized correlation between KS and various neuropsychiatric conditions, studies investigating potential sleep disorders, particularly in pediatric subjects, are lacking.
