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 ...
EPFL2024In 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 ...
2024Interfacing 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 ...
2023Dopamine Dynamics in Reward-based Learning
Dopamine signals are thought to be important for reward-based learning and appear to play important roles in regulating synaptic plasticity in the nucleus accumbens and the striatum. However, the precise neuronal circuit mechanisms underlying the learning ...
