Nature Communications, 2020 Alterations of locus coeruleus signal intensity have been associated with functional changes in health and disease. Here, the authors tested a pre-registered hypothesis on a large number of subjects as part of the Cam-CAN consortium.

2D Locus Configurations and the Charged Trigonometric Calogero-Moser System [PDF]
, 2010 A central hyperplane arrangement in C^2 with multiplicity is called a `locus configuration' if it satisfies a series of `locus equations' on each hyperplane. Following Chalykh, Feigin and Veselov [CFV99], we demonstrate that the first locus equation for each hyperplane corresponds to a force-balancing equation on a related interacting particle system ...

Concealed identity information detection with pupillometry in rapid serial visual presentation
Psychophysiology, Volume 60, Issue 1, January 2023., 2023 Abstract The concealed information test (CIT) relies on bodily reactions to stimuli that are hidden in mind. However, people can use countermeasures, such as purposely focusing on irrelevant things, to confound the CIT. A new method designed to prevent countermeasures uses rapid serial visual presentation (RSVP) to present stimuli on the fringe of ...

Locus Coeruleus and Dopamine-Dependent Memory Consolidation
Neural Plasticity, 2017 Most everyday memories including many episodic-like memories that we may form automatically in the hippocampus (HPC) are forgotten, while some of them are retained for a long time by a memory stabilization process, called initial memory consolidation ...

Psychophysiology, Volume 60, Issue 1, January 2023., 2023 Abstract Actions modulate sensory processing by attenuating responses to self‐ compared to externally generated inputs, which is traditionally attributed to stimulus‐specific motor predictions. Yet, suppression has been also found for stimuli merely coinciding with actions, pointing to unspecific processes that may be driven by neuromodulatory systems.

iScience, 2020 Summary: Little is known about the real-time cellular dynamics triggered by endogenous catecholamine release despite their importance in brain functions. To address this issue, we expressed channelrhodopsin in locus coeruleus neurons and protein kinase-A

Research progress on the mechanisms of pain empathy
Ibrain, EarlyView.This article is related to the graphical research progress of pain empathy, starting with the description of the pain matrix and mirror neurons. Based on the pain matrix and mirror neurons, pain empathy results from the combined action of brain regions such as the anterior cingulate cortex, insula, prefrontal cortex, and amygdala and regulatory ...

Simplified models of pacemaker spiking in raphe and locus coeruleus neurons [PDF]
arXiv, 2015 Many central neurons, and in particular certain brainstem aminergic neurons exhibit spontaneous and fairly regular spiking with frequencies of order a few Hz. A large number of ion channel types contribute to such spiking so that accurate modeling of spike generation leads to the requirement of solving very large systems of differential equations ...

Progress of non‐motor symptoms in early‐onset Parkinson's disease
Ibrain, EarlyView.This study reviews the research progress related to non‐motor symptoms (NMS) in patients with early onset Parkinson's disease (EOPD), including neuropsychiatric symptoms, autonomic dysfunction, sleep disorders, and sensory disorders and also summarizes the characteristics of NMS in the genetic form of Parkinson's disease (PD).

The Gut‐Brain Axis in Parkinson disease: Emerging Concepts and Therapeutic Implications
Movement Disorders Clinical Practice, EarlyView.Abstract Background The gut‐brain axis, i.e. the bidirectional communication system between the gut and the brain, has become of central importance in Parkinson disease (PD) research over the past 20 years. Aims We aimed to describe the milestones of the gut‐brain axis research in PD and the development of theories proposing the involvement of the ...
