Pierre Theopistos Vassiliadis, Julie Duqué

Reward timing, that is, the delay after which reward is delivered following an action is known to strongly influence reinforcement learning. Here, we asked if reward timing could also modulate how people learn and consolidate new motor skills. In 60 health ...

Dopamine Transporter, PhosphoSerine129 alpha-Synuclein and alpha-Synuclein Levels in Aged LRRK2 G2019S Knock-In and Knock-Out Mice

Salvatore Novello, Chiara Domenicale

The G2019S mutation in leucine rich-repeat kinase 2 (LRRK2) is a major cause of familial Parkinson's disease. We previously reported that G2019S knock-in mice manifest dopamine transporter dysfunction and phosphoSerine129 alpha-synuclein (pSer129 alpha-syn ...

Striatal dopamine explains novelty-induced behavioral dynamics and individual variability in threat prediction

Alexander Mathis, Mackenzie Mathis

Animals both explore and avoid novel objects in the environment, but the neural mechanisms that underlie these behaviors and their dynamics remain uncharacterized. Here, we used multi-point tracking (DeepLabCut) and behavioral segmentation (MoSeq) to chara ...

What Makes for Automatic Reconstruction of Pulmonary Segments

Jiancheng Yang, Li Zhang, Hongwei Li, Bo Du, Jingyu Li

3D reconstruction of pulmonary segments plays an important role in surgical treatment planning of lung cancer, which facilitates preservation of pulmonary function and helps ensure low recurrence rates. However, automatic reconstruction of pulmonary segmen ...

Obesity-associated deficits in inhibitory control are phenocopied to mice through gut microbiota changes in one-carbon and aromatic amino acids metabolic pathways

Xavier Fernandez-Real Girona

Background Inhibitory control (IC) is critical to keep long-term goals in everyday life. Bidirectional relationships between IC deficits and obesity are behind unhealthy eating and physical exercise habits. Methods We studied gut microbiome composition and ...

Amplified engagement of prefrontal cortex during control of voluntary action in Tourette syndrome

Sophie Jacqueline Andrée Betka

Tourette syndrome is characterized by 'unvoluntary' tics, which are compulsive, yet often temporarily suppressible. The inferior frontal gyms is implicated in motor control, including inhibition of pre-potent actions through influences on downstream subcor ...

Latency to Reward Predicts Social Dominance in Rats: A Causal Role for the Dopaminergic Mesolimbic System

Maria del Carmen Sandi Perez, Simone Astori, Ioannis Zalachoras, Laura Lozano Montes, Sonia Abad Florensa

Reward signals encoded in the mesolimbic dopaminergic system guide approach/seeking behaviors to all varieties of life-supporting stimuli (rewards). Differences in dopamine (DA) levels have been found between dominant and submissive animals. However, it is ...

Time intermittency in nondiffusive transport regimes of suprathermal ions in turbulent plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Marcelo Baquero Ruiz, Oulfa Chellaï, Fabian Manke

Intermittent phenomena have long been studied in the context of nondiffusive transport across a variety of fields. In the TORPEX device, the cross-field spreading of an injected suprathermal ion beam by electrostatic plasma turbulence can access different ...
