Galaninergic and hypercapnia-activated neuronal projections to the ventral respiratory column.

In mammals, the ventral respiratory column (VRC) plays a pivotal role in integrating neurochemically diverse inputs from brainstem and forebrain regions to generate respiratory motor patterns. VRC microinjection of the neuropeptide galanin has been reported to dampen carbon dioxide (CO)-mediated chemoreflex responses. Additionally, we previously demonstrated that galaninergic neurons in the retrotrapezoid nucleus (RTN) are implicated in the adaptive response to hypercapnic stimuli, suggesting a link between RTN neuroplasticity and increased neuronal drive to the VRC.

Psychiatric emergencies among urban youth during COVID-19: Volume and acuity in a multi-channel program for the publicly insured.

This study sought to characterize changes in the utilization of psychiatric emergency services among children and adolescents during distinct phases of 2020, as compared with prior years. We conducted a retrospective review of electronic health records from January 2018 through December 2020 that included all encounters made by patients under age 21. We then analyzed data for the 15,045 youth psychiatric encounters during the study period.

Prospective F-18 FDOPA PET Imaging Study in Human PD.

Purpose: We present the findings of our final prospective study submitted to the U.S. Food and Drug Administration (FDA) for New Drug Application (NDA) approval for the use of 3,4-dihydroxy-6-[18F]fluoro-l-phenylalanine (F-18 FDOPA) positron emission tomography (PET) imaging for Parkinson's disease (PD).

Systematic Review and Meta-Analysis of Token Economy Practices in K-5 Educational Settings, 2000 to 2019.

Token economy systems have been widely used as an evidence-based classroom management strategy to reinforce and improve prosocial responses. While token economies have been widely applied to educational settings, there have been mixed results regarding the effectiveness depending on the classroom type. To better understand the components contributing to the effectiveness, the researchers analyzed 24 token economy studies conducted in general and special education classrooms from kindergarten to fifth grade between 2000 and 2019.

Hemispheric Network Expression in Parkinson's Disease: Relationship to Dopaminergic Asymmetries.

Background: Parkinson's disease (PD) is characterized by brain metabolic networks, specifically associated with motor and cognitive manifestations. Few studies have investigated network changes in cerebral hemispheres ipsilateral and contralateral to the clinically more affected body side.

Objective: We examined hemispheric network abnormalities and their relationship to striatal dopaminergic deficits in PD patients at different stages.

K-EmoCon, a multimodal sensor dataset for continuous emotion recognition in naturalistic conversations.

Recognizing emotions during social interactions has many potential applications with the popularization of low-cost mobile sensors, but a challenge remains with the lack of naturalistic affective interaction data. Most existing emotion datasets do not support studying idiosyncratic emotions arising in the wild as they were collected in constrained environments. Therefore, studying emotions in the context of social interactions requires a novel dataset, and K-EmoCon is such a multimodal dataset with comprehensive annotations of continuous emotions during naturalistic conversations.

Understanding Editing Behaviors in Multilingual Wikipedia.

Multilingualism is common offline, but we have a more limited understanding of the ways multilingualism is displayed online and the roles that multilinguals play in the spread of content between speakers of different languages. We take a computational approach to studying multilingualism using one of the largest user-generated content platforms, Wikipedia. We study multilingualism by collecting and analyzing a large dataset of the content written by multilingual editors of the English, German, and Spanish editions of Wikipedia.
