IR Spectroscopy: Molecular Vibration Overview01:24

IR Spectroscopy: Molecular Vibration Overview

When Infrared (IR) radiation passes through a covalently bonded molecule, the bonds transition from lower to higher vibrational levels. The fundamental vibrational motions that result in infrared absorption can be classified as stretching or bending vibrations.
Stretching vibrations are vibrational motions that occur along the bond line, changing the bond length or distance between two bonded atoms. They are further distinguished as symmetric or asymmetric. In symmetric stretching, the...

IR Spectroscopy: Hooke's Law Approximation of Molecular Vibration

A covalently bonded heteronuclear diatomic molecule can be modeled as two vibrating masses connected by a spring. The vibrational frequency of the bond can be expressed using an equation derived from Hooke's law, which describes how the force applied to stretch or compress a spring is proportional to the displacement of the spring. In this case, the atoms behave like masses, and the bond acts like a spring.
According to Hooke's law, the vibrational frequency is directly proportional to the...

Protein Dynamics in Living Cells

Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

Summary

Motion artifacts in functional near-infrared spectroscopy (fNIRS) require tailored correction. Optimal methods for resting-state data depend on artifact type and severity, with specific strategies outperforming others under different contamination levels.

Area of Science:

  • Neuroimaging
  • Biomedical Engineering
  • Signal Processing

Background:

  • Motion artifacts pose a significant challenge in functional near-infrared spectroscopy (fNIRS) data acquisition.
  • Effective strategies for mitigating motion artifacts in resting-state fNIRS data remain underexplored.

Purpose of the Study:

  • To evaluate the impact of various motion artifact correction techniques on functional connectivity analysis in resting-state fNIRS.
  • To determine the optimal correction approach based on the type and extent of motion contamination.

Main Methods:

  • Utilized semi-simulated resting-state fNIRS datasets with controlled spike-like and baseline-shift motion artifacts.
  • Applied fifteen distinct preprocessing pipelines with varying motion correction strategies.
  • Assessed pipeline performance using three quantitative metrics on group-level functional connectivity.

Main Results:

  • Multiple correction approaches proved effective at low contamination levels.
  • Pipeline reliability decreased significantly with increased motion artifact contamination.
  • Discarding frames post-preprocessing was optimal for datasets with minimal baseline shifts, while pre-processing frame discarding was superior when both artifact types were present.

Conclusions:

  • The efficacy of motion artifact correction in fNIRS is highly dependent on the specific characteristics of the artifacts.
  • A one-size-fits-all approach is insufficient; customized strategies are necessary for robust resting-state functional connectivity analysis.
