Dopamine neurons projecting to the posterior striatum reinforce avoidance of threatening stimuli
Nature Neuroscience, 2018 Midbrain dopamine neurons are well known for their role in reward-based reinforcement learning. We found that the activity of dopamine axons in the posterior tail of the striatum (TS) scaled with the novelty and intensity of external stimuli, but did not

Midbrain dopamine neurons signal aversion in a reward-context-dependent manner
eLife, 2016 Dopamine is thought to regulate learning from appetitive and aversive events. Here we examined how optogenetically-identified dopamine neurons in the lateral ventral tegmental area of mice respond to aversive events in different conditions. In low reward

Inclusion of Enclosed Hydration Effects in the Binding Free Energy Estimation of Dopamine D3 Receptor Complexes [PDF]
, 2019 Confined hydration and conformational flexibility are some of the challenges encountered for the rational design of selective antagonists of G-protein coupled receptors. We present a set of C3-substituted (-)-stepholidine derivatives as potent binders of the dopamine D3 receptor.

Dopamine neurons create Pavlovian conditioned stimuli with circuit-defined motivational properties
Nature Neuroscience, 2018 Environmental cues, through Pavlovian learning, become conditioned stimuli that guide animals toward the acquisition of rewards (for example, food) that are necessary for survival. We tested the fundamental role of midbrain dopamine neurons in conferring

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration
Advanced Functional Materials, EarlyView.A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Electronic schematic for bio-plausible dopamine neuromodulation of eSTDP and iSTDP [PDF]
arXiv, 2018 In this technical report we present novel results of the dopamine bio-plausible neuromodulation excitatory (eSTDP) and inhibitory (iSTDP) learning. We present the principal schematic for the neuromodulation of D1 and D2 receptors of dopamine, wiring schematic for both cases as well as the simulatory experiments results done in LTSpice.

Performance of dopamine modified 0.5(Ba0.7Ca0.3)TiO3-0.5Ba(Zr0.2Ti0.8)O3 filler in PVDF nanocomposite as flexible energy storage and harvester [PDF]
arXiv, 2021 We demonstrate the potential of dopamine modified 0.5(Ba0.7Ca0.3)TiO3-0.5Ba(Zr0.2Ti0.8)O3 filler incorporated poly-vinylidene fluoride (PVDF) composite prepared by solution cast method as both flexible energy storage and harvesting devices. The introduction of dopamine in filler surface functionalization acts as bridging elements between filler and ...

Interactions of dopamine and dopamine hydrochloride with ethanol [PDF]
Journal of Molecular Liquids, 2016 Abstract Cyclic voltammetry (CV), density functional theory (DFT) calculations, and atoms in molecules (AIM) analyses were performed to investigate the hydrogen bonding in dopamine-ethanol and dopamine hydrochloride-ethanol mixtures. CV results show that the anodic/cathodic peak potential of dopamine hydrochloride in ethanol is influenced by the ...
