Audio–visual Reaction Time in Different Age Groups in Normal Individuals: A Cross-sectional Study

Journal of the Scientific Society
Background: Reaction time (RT) is a simple yet sensitive measure of sensorimotor and cognitive processing. As life expectancy increases, understanding age-related changes in RT is essential to assess the functional implications of aging on everyday tasks

Effect of posture on reaction time: Impact of gender

National Journal of Physiology, Pharmacy and Pharmacology, 2020
Background: Reaction time (RT) is a reliable parameter of functional capacity of the central nervous system and a non-invasive method of determining coordination between sensory and motor systems and reflex activity of a person.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

The effect of acute vibration on visual reaction time in fencers

Sportis. Scientific Journal of School Sport, Physical Education and Psychomotricity, 2020
The purpose of this study is to determine the effect of an acute local vibration exercise on the visual reaction time of a fencer’s upper body extremities. Twenty-six male fencers between the ages of 15 and 23 (mean age, 17.38 ± 2.13 years, height: 173.6±9.1 cm, body mass: 70.2 ±14.1 kg) volunteered for this study.

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 ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Reaction time distributions constrain models of visual search

Vision Research, 2010
Many experiments have investigated visual search for simple stimuli like colored bars or alphanumeric characters. When eye movements are not a limiting factor, these tasks tend to produce roughly linear functions relating reaction time (RT) to the number of items in the display (set size).

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Delayed inhibition of an anticipatory action during motion extrapolation [PDF]

, 2010
Background: Continuous visual information is important for movement initiation in a variety of motor tasks. However, even in the absence of visual information people are able to initiate their responses by using motion extrapolation processes ...
