Using a specialized magnetic resonance imaging (MRI) sensor that can track dopamine levels, neuroscientists have discovered how dopamine released deep within the brain influences distant brain regions ...

Using a specialized magnetic resonance imaging (MRI) sensor, MIT neuroscientists have discovered how dopamine released deep within the brain influences both nearby and distant brain regions. Dopamine ...

Rewards direct behavioral adaptation through midbrain dopamine signaling, though the timing of those effects is often ambiguous. Lee and colleagues find that different subpopulations of dopamine ...

UC Davis neuroscientist Lin Tian and her team, Tommaso Patriarchi, Gerard Broussard and Ruqiang Liang, have developed fluorescence sensors that are opening a new era for the optical recording of ...

Research in mice has shown how exercise increases levels of a chemical called brain-derived neurotrophic factor (BDNF), which bolsters the release of the “feel-good” hormone dopamine (DA). DA is known ...

Adaptive behavior requires learning which actions lead to desired outcomes and updating this knowledge when the world changes. Reinforcement learning (RL) has provided an influential account of how ...

Researchers at Kanazawa University identified dopamine-driven neural mechanisms of motivation in a mouse model of behavioral addiction, offering insights into treatment. Assistant Professor Naoya ...

The role of dopamine in REM sleep, dream recall, and dream content has come under increasingly stronger scrutiny in recent years. This is theoretically important for understanding sleep and dreams ...

Stressful situations tend to reduce the drive to mate across many animal species, but the exact brain mechanisms behind this ...

CAMBRIDGE, MA -- Using a specialized magnetic resonance imaging (MRI) sensor, MIT neuroscientists have discovered how dopamine released deep within the brain influences both nearby and distant brain ...
