TL;DR: It is shown that DBS selectively interferes with the normal ability to slow down when faced with decision conflict, which implicate independent mechanisms leading to impulsivity in treated Parkinson's patients and were predicted by a single neurocomputational model of the basal ganglia.

TL;DR: A neurocomputational dissociation between striatal and prefrontal dopaminergic mechanisms in reinforcement learning is supported and independent gene effects on three reinforcement learning parameters that can explain the observed dissociations are revealed.

TL;DR: Using a genome-wide approach to estimate the “green” contribution to diatoms, it is identified >1700 green gene transfers, constituting 16% of the diatom nuclear coding potential.

TL;DR: The finding that dopamine agonists administration in young patients with Parkinson's disease resulted in increased novelty seeking, enhanced reward processing, and decreased punishment processing may shed light on the cognitive and personality bases of the impulse control disorders, which arise as side-effects of dopamine agonist therapy in some Parkinson's patients.

TL;DR: An evolutionary scenario involving an ancestral red alga that was driven by early ecological forces to lose genes, introns, and intergenetic DNA is proposed; this loss was followed by an expansion of genome size as a consequence of activity of transposable elements.
