A role for locus coeruleus in Parkinson tremor
Frontiers in Human Neuroscience, 2012 We analyzed rest tremor, one of the aetiologically most elusive hallmarks of Parkinson disease (PD), in 12 consecutive PD patients during a specific task activating the locus coeruleus (LC) to investigate a putative role of noradrenaline (NA) in tremor ...

Splitting Root-Locus Plot into Algebraic Plane Curves [PDF]
arXiv, 2015 In this paper we show how to split the Root Locus plot for an irreducible rational transfer function into several individual algebraic plane curves, like lines, circles, conics, etc. To achieve this goal we use results of a previous paper of the author to represent the Root Locus as an algebraic variety generated by an ideal over a polynomial ring, and

Cell Reports, 2018 Summary: How general anesthesia causes loss of consciousness has been a mystery for decades. It is generally thought that arousal-related brain nuclei, including the locus coeruleus (LC), are involved.

Hodge locus and Brill-Noether type locus [PDF]
arXiv, 2016 Given a family $\pi:\mc{X} \rightarrow B$ of smooth projective varieties, a closed fiber $\mc{X}_o$ and an invertible sheaf $\mc{L}$ on $\mc{X}_o$, we compare the Hodge locus in $B$ corresponding to the Hodge class $c_1(\mc{L})$ with the locus of points $b\,\in\, B$ such that $\mc{L}$ deforms to an invertible sheaf $\mc{L}_b$ on $\mc{X}_b$ with at ...

Brain Pathology, EarlyView.(A) PPN‐cholinergic neurons degenerate during PD. We stereologically counted their rostro‐caudal distribution in post‐mortem PPNs in health versus PD. (Bi) Serial PPN‐containing samples were cholinergic antibody‐DAB stained. (Bii) Only DAB‐stained neurons on green lines and inside the box were counted.

Dynamic Neural Curiosity Enhances Learning Flexibility for Autonomous Goal Discovery [PDF]
arXivThe autonomous learning of new goals in robotics remains a complex issue to address. Here, we propose a model where curiosity influence learning flexibility. To do so, this paper proposes to root curiosity and attention together by taking inspiration from the Locus Coeruleus-Norepinephrine system along with various cognitive processes such as cognitive

The locus of log canonical singularities [PDF]
arXiv, 1998 The LCS locus is an essential ingredient in the proof of fundamental results of Log Minimal Model Program, such as nonvanishing and base point freeness theorems. We prove in this paper that the LCS locus of a log canonical variety has seminormal singularities.
