Predicting Fear Extinction in Posttraumatic Stress Disorder

Brain Sciences, 2023
Fear extinction is the basis of exposure therapies for posttraumatic stress disorder (PTSD), but half of patients do not improve. Predicting fear extinction in individuals with PTSD may inform personalized exposure therapy development.

[18F]Fluorodeprenyl‐D2 PET as a Tool to Monitor Disease Activity in GAD65‐Ab Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate [18F]fluorodeprenyl‐D2 ([18F]F‐DED) positron‐emission tomography (PET) imaging as a biomarker of disease activity in autoimmune encephalitis (AIE) associated with glutamic acid decarboxylase 65 (GAD65) antibodies. Methods [18F]F‐DED PET was performed in 25 GAD65‐AIE patients and 8 controls using dynamic (0–60 min) and ...

The Effects of Startle and Non-Startle Auditory Stimuli on Wrist Flexion Movement in Parkinson's Disease [PDF]

, 2013
[Abstract] Startle stimuli lead to shorter reaction times in control subjects and Parkinson's disease (PD) patients. However, non-startle stimuli also enhance movement initiation in PD.

The Effects of Sertraline administration from adolescence to adulthood on physiological and emotional development in prenatally stressed rats of both sexes

Frontiers in Behavioral Neuroscience, 2014
Sertraline is a clinically effective Selective Serotonin Reuptake Inhibitor known to increase and stabilize serotonin levels. This neurotransmitter plays an important role in adolescent brain development in both rodents and humans, and its dysregulation ...

Maternal Separation Induces Sex-Specific Differences in Sensitivity to Traumatic Stress

Frontiers in Behavioral Neuroscience, 2021
Post-traumatic stress disorder (PTSD) is a debilitating psychiatric disorder with a high economic burden. Two risk factors for increasing the chances of developing PTSD are sex (being female) and early life stress.

In vivo Ca2+ imaging reveals that decreased dendritic excitability drives startle habituation

Cell Reports, 2015
Summary Exposure to repetitive startling stimuli induces habitation, a simple form of learning. Despite its simplicity, the precise cellular mechanisms by which repeated stimulation converts a robust behavioral response to behavioral indifference are ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Pre-Learning Stress That Is Temporally Removed from Acquisition Impairs Fear Learning

Biology, 2023
Few studies have examined the time-dependent effects of stress on fear learning. Previously, we found that stress immediately before fear conditioning enhanced fear learning.

Startling speech: eliciting prepared speech using startling auditory stimulus [PDF]

Frontiers in Psychology, 2014
Speech research has recently seen a good deal of activity surrounding forward models (Tian and Poeppel, 2012; Pickering and Garrod, 2013; Scott, 2013), expanding on a long tradition of work in preprogramming of speech motor plans (e.g., Lashley, 1951; Keele, 1981; Klapp, 2003).

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
