Unveiling the complexity of learning and decision-making

Reinforcement learning (RL) is crucial for learning to adapt to new environments. In RL, the prediction error is an important component that compares the expected and actual rewards. Dopamine plays a critical role in encoding these prediction errors. In my ...

In vivo polydopamine coating of Rhodobacter sphaeroides for enhanced electron transfer

Ardemis Anoush Boghossian, Melania Reggente, Fabian Fischer

Recent advances in coupling light-harvesting microorganisms with electronic components have led to a new generation of biohybrid devices based on microbial photocatalysts. These devices are limited by the poorly conductive interface between phototrophs and ...

Interfacing aptamer-modified nanopipettes with neuronal media and ex vivo brain tissue

Nako Nakatsuka, Anna Burdina, Annina Stuber

Aptamer-functionalized biosensors exhibit high selectivity for monitoring neurotransmitters in complex environments. We translated nanoscale aptamer-modified nanopipette sensors to detect endogenous dopamine release in vitro and ex vivo. These sensors empl ...

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 ...

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 ...

Computationally-guided tuning of ligand sensitivity in a GPCR-based sensor

Patrick Daniel Barth, Dániel Kéri

Genetically-encoded fluorescent sensors for neuromodulators are increasingly used molecular tools in neuroscience. However, these protein-based biosensors are often limited by the sensitivity of the protein scaffold towards endogenous ligands. Here, we exp ...

Parkinson mice show functional and molecular changes in the gut long before motoric disease onset

Hilal Lashuel, Yang Liu

Background: There is increasing evidence that Parkinson's disease (PD) might start in the gut, thus involving and compromising also the enteric nervous system (ENS). At the clinical onset of the disease the majority of dopaminergic neurons in the midbrain ...

In-flow electrochemical detection of chemicals in droplets with pyrolysed photoresist electrodes: application as a module for quantification of microsampled dopamine

Philippe Renaud, Arnaud Bertsch, Joan Teixidor, Albert René Yvon Leroy

The electrochemical quantification of analytes in droplets of PBS separated by a fluorinated phase was investigated. PDMS-fused silica chips with pyrolysed photoresist electrodes were prepared using a simple fabrication technique and used to analyze drople ...

Structure of a D2 dopamine receptor-G-protein complex in a lipid membrane

Patrick Daniel Barth, Mahdi Hijazi

The D2 dopamine receptor (DRD2) is a therapeutic target for Parkinson's disease(1)and antipsychotic drugs(2). DRD2 is activated by the endogenous neurotransmitter dopamine and synthetic agonist drugs such as bromocriptine(3), leading to stimulation of G(i) ...

The glucocorticoid receptor in the nucleus accumbens plays a crucial role in social rank attainment in rodents

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Fiona Hollis, Ioannis Zalachoras, Meltem Weger, Thomas Didier Larrieu, Alexandre Claude Gustave Bacq

Social hierarchy in social species is usually established through competitive encounters with conspecifics. It determines the access to limited resources and, thus, leads to reduced fights among individuals within a group. Despite the known importance of s ...
