The Origin of Abnormal Beta Oscillations in the Parkinsonian Corticobasal Ganglia Circuits
TL;DR: Changes of neuronal activity observed in experimental PD models are reviewed and how the cortex and different BG nuclei cooperate to generate and stabilize abnormal beta oscillations during parkinsonism is discussed, which may provide further insights into the complex relationship between abnormal Beta oscillations and motor dysfunction in PD.

TL;DR: This work finds that the secretogranin II gene (Scg2) was cooperatively activated by glutamate and dopamine in primary cultured mouse hippocampal neurons and proposes that the regulatory system of Scg2 expression is equipped with machinery that is refined for the signal integration of in‐phase synaptic inputs.

TL;DR: Results suggest that, in the healthy system, synchrony between neurotransmitter (DA) and hemodynamic (BOLD) systems optimizes the level of BOLD activation evoked for a given DA input, facilitating task performance, and desynchronization between these brain systems would reduce the gain parameter of this function, adversely impacting task performance and contributing to reduced face recognition in older adults.

Survival of the salient: Aversive learning rescues otherwise forgettable memories via neural reactivation and post-encoding hippocampal connectivity
TL;DR: In this paper , the effects of aversive events on memory are complex and go beyond the simple enhancement of threatening information, negative experiences can also rescue related but otherwise forgettable details encoded close in time.

TL;DR: In this article, the locus coeruleus-norepinephrine (LC-NE) system plays a more complex and specific role in the control of behavior than investigators previously thought.

TL;DR: For instance, Craik and Lockhart as discussed by the authors explored the levels of processing framework for human memory research and found that deeper encodings took longer to accomplish and were associated with higher levels of performance on the subsequent memory test.
