Habituation of reflexive and motivated behaviour in mice with deficient BK channel function

Frontiers in Integrative Neuroscience, 2013
Habituation is considered the most basic form of learning. It describes the decrease of a behavioural response to a repeated non-threatening sensory stimulus and therefore provides an important sensory filtering mechanism.

Startle Increases the Incidence of Anticipatory Muscle Activations but Does Not Change the Task-Specific Muscle Onset for Patients After Subacute Stroke

Frontiers in Neurology, 2022
Objectives: To demonstrate the task-specificities of anticipatory muscle activations (AMAs) among different forward-reaching tasks and to explore the StartleReact Effect (SE) on AMAs in occurrence proportions, AMA onset latency or amplitude within these ...

Startle Responses in Hereditary Hyperekplexia [PDF]

Archives of Neurology, 1997
Patients with hereditary hyperekplexia have excessive startle responses that are accompanied by transient stiffness and also continuous stiffness in infancy. A point of mutation has been identified for the major form of hereditary hyperekplexia in the gene encoding the alpha 1 subunit of the glycine receptor.To measure startle reflexes and autonomic ...

Subcellular Dissection of a Simple Neural Circuit: Functional Domains of the Mauthner-Cell During Habituation

Frontiers in Neural Circuits, 2021
Sensorimotor integration is a pivotal feature of the nervous system for ensuring a coordinated motor response to external stimuli. In essence, such neural circuits can optimize behavioral performance based on the saliency of environmental cues.

Habituation of the startle reflex depends on attention in cannabis users

BMC Psychology, 2016
Background Cannabis use is associated with an attention-dependent deficit in prepulse inhibition of the startle reflex (PPI). The aim of the current study was to investigate startle habituation in cannabis users and healthy controls during two ...

A forward genetic screen identifies Dolk as a regulator of startle magnitude through the potassium channel subunit Kv1.1.

PLoS Genetics, 2021
The acoustic startle response is an evolutionarily conserved avoidance behavior. Disruptions in startle behavior, particularly startle magnitude, are a hallmark of several human neurological disorders.

Model Gender Interacts With Expressed Emotion to Enhance Startle: Angry Male and Happy Female Faces Produce the Greatest Potentiation

Frontiers in Human Neuroscience, 2020
Several studies have implied gender differences in startle reaction to emotional facial expressions. However, few studies have been designed to investigate the difference between responding to emotional female vs.

Fear-potentiated startle: a review from an aviation perspective

, 2015
Pilot performance following unexpected critical events has been either ineffective or inappropriate in some recent aircraft accidents. The deleterious effects of startle have been identified as causal or contributory in these events.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

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.
