A role for nonapeptides and dopamine in nest-building behaviour [PDF]

, 2015
During nest building in zebra finches (Taeniopygia guttata), several regions in the social behaviour network and the dopaminergic reward system, two neural circuits involved in social behaviour, appear to be active in male and female nest-building ...

Mesolimbic dopamine ramps reflect environmental timescales

eLife
Mesolimbic dopamine activity occasionally exhibits ramping dynamics, reigniting debate on theories of dopamine signaling. This debate is ongoing partly because the experimental conditions under which dopamine ramps emerge remain poorly understood.

Optogenetic stimulation of VTA dopamine neurons reveals that tonic but not phasic patterns of dopamine transmission reduce ethanol self-administration

Frontiers in Behavioral Neuroscience, 2013
There is compelling evidence that acute ethanol exposure stimulates ventral tegmental area (VTA) dopamine cell activity and that VTA-dependent dopamine release in terminal fields within the nucleus accumbens plays an integral role in the regulation of ...

Conjugated Metal‐Organic Frameworks on Laser‐Induced‐Graphene Scaffold Enable Picomolar Sensitivity in Electrical Biosensors

Advanced Materials Interfaces, EarlyView.
A controlled layer‐by‐layer growth process integrates conjugated metal‐organic framework thin films onto a hierarchical 3D laser‐induced graphene scaffold. When incorporated into an extended‐gate field‐effect transistor configuration, this synergistic hybrid platform achieves robust aptamer immobilization, driving highly selective, picomolar‐level ...

High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

Advanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Dopamine and Risk Preferences in Different Domains [PDF]

Individuals differ significantly in their willingness to take risks. Such differences may stem, at least in part, from individual biological (genetic) differences.

Dopamine transporters and the nanoscale organization of the dopamine axon [PDF]

Dopamine is released from numerous varicosities (or boutons-en-passant) along the extensive axonal network of dopaminergic neurons. Because of the small size of dopamine varicosities (
