Effect of Mahamantra Chanting on Autonomic and Cognitive Functions- An Interventional Study [PDF]

Journal of Clinical and Diagnostic Research, 2019
Introduction: Stress is a major health issue which leads to several potential negative health and well-being outcomes. Early interventions like yoga, meditation and music can reduce stress induced morbidity and mortality.

CONTRAST AS SEEN IN VISUAL SEARCH REACTION TIMES [PDF]

Journal of the Experimental Analysis of Behavior, 1989
Three pigeons searched arrays of alphabetic letters displayed on computer monitors. On each trial, either an A or an E appeared, and the reaction time and accuracy with which the bird pecked at this target were measured. In each block of trials, each target (A or E) was displayed alone, or together with a number of distractor letters (2 or 18) that ...

Effect of smoking on visual evoked potential (VEP) and visual reaction time (VRT)

Asian Journal of Medical Sciences, 2020
Background: Nicotine in tobacco smoke causes demyelination. Again, hypoxia in long-term smokers is linked to neuropathy. Visual receptors are early sufferer of neuropathy.

Stimulus saliency modulates pre-attentive processing speed in human visual cortex [PDF]

, 2011
The notion of a saliency-based processing architecture [1] underlying human vision is central to a number of current theories of visual selective attention [e.g., 2].

Reaction time to change in visual orientation [PDF]

Perception & Psychophysics, 1972
The aftereffects of viewing diagonal lines for 50, 500, and 1,000 msec were measured by the speed and accuracy of identification of a variably tilted test grating. Significant RT and tilt aftereffects were found as functions of the duration of orientation-specific adaptation and the angle of separation between inspection and test lines.

Sit-and-Wait Strategies in Dynamic Visual Search [PDF]

, 2003
The role of memory in visual search has lately become a controversial issue. Horowitz and Wolfe (1998) observed that performance in a visual search task was little affected by whether the stimuli were static or randomly relocated every 111 ms.

Effects of various distractions on audio and visual reaction time in 1st year MBBS students

National Journal of Physiology, Pharmacy and Pharmacology, 2019
Background: Reaction time (RT) defines as it is time between the presentation of a sensory stimulus and the subsequent response. Simple RT is defined as the time required for an observer to find out the presence of a stimulus.

Reaction time in a visual 4-choice reaction time task: ERP effects of motor preparation and hemispheric involvement [PDF]

, 2016
Reaction time (RT), the most common measure of CNS efficiency, shows intra- and inter-individual variability. This may be accounted for by hemispheric specialization, individual neuroanatomy, and transient functional fluctuations between trials.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
