Mismatch Repair

6.3K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

Load-frequency control

Load-frequency control (LFC) is vital for maintaining power system stability, ensuring that frequency and power flows remain within acceptable limits during load changes. Turbine-governor control eliminates rotor accelerations and decelerations following load changes. However, a steady-state frequency error persists when the change in the turbine-governor reference setting is zero. In an interconnected power system, each area agrees to export or import a scheduled amount of power through...

In the back of everyone's eye is a small piece of neural tissue called the retina. The retina has photosensitive cells that respond to stimulation by light. The responses of these cells are sent into the brain through the optic nerve, a bundle of neural fibers. In each retina there is a place somewhere in the periphery where the outputs from retinal cells collect and the bundled optic nerve exits to the brain. At that...

Psychophysics is the name for a set of methods in perceptual psychology designed in order to relate the actual intensity of stimuli to their perceptual intensity. One important aspect of psychophysics involves the measurement of perceptual thresholds: How bright does a light need to be for a person to be able to detect it? How little pressure applied to the skin is detectable? How soft can a sound be and still be heard? Put...

Summary
This summary is machine-generated.

Visual task difficulty does not affect auditory mismatch negativity (MMN). This auditory perception measure remains robust, even when working memory capacity is considered, suggesting crossmodal attention does not influence MMN.

Area of Science:

  • Auditory Neuroscience
  • Cognitive Psychology
  • Perceptual Science

Background:

  • Mismatch negativity (MMN) is a sensitive auditory event-related potential reflecting auditory change detection.
  • Previous research suggested MMN is reduced by concurrent visual tasks, but replication has been inconsistent.
  • Concerns about biased findings and methodological confounds (e.g., physical tone differences) prompted this investigation.

Purpose of the Study:

  • To rigorously test the effect of visual task difficulty on MMN using Bayesian hypothesis testing.
  • To investigate whether a corrected MMN measure is also affected by visual load.
  • To examine the moderating role of working memory capacity in the relationship between visual load and MMN.

Main Methods:

  • Participants (N=49) performed auditory oddball tasks with varying visual perceptual load (high vs. low).
  • Both oddball MMN and a corrected MMN (deviant minus critical tones) were measured.
  • Bayesian hypothesis testing (BF01) quantified evidence for or against an effect of visual load.
  • Working memory capacity was assessed to explore its moderating influence.

Main Results:

  • Bayesian analysis provided moderate evidence for no effect of visual load on oddball MMN (9.09 > BF01 > 3.57).
  • Evidence for no effect was anecdotal to moderate for the corrected MMN (4.55 > BF01 > 2.17).
  • Working memory capacity did not correlate with any observed visual load effects on MMN measures.

Conclusions:

  • The auditory frequency MMN is robust to manipulations of crossmodal visual attention and task difficulty.
  • The findings challenge previous assumptions about MMN's susceptibility to attentional load.
  • Working memory capacity does not appear to moderate the relationship between visual attention and MMN.
