Olfactory Receptors: Location and Structure

9.9K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Summary

Brain structural connectivity changes, particularly in the right internal capsule, are linked to aspiration after stroke. This finding may help identify patients at risk for aspiration pneumonia.

Area of Science:

  • Neuroscience
  • Neurology
  • Stroke Research

Background:

  • Aspiration after stroke increases risks of pneumonia and mortality.
  • Understanding the neural basis of post-stroke aspiration is crucial for patient outcomes.

Purpose of the Study:

  • To investigate brain structural connectivity associated with aspiration in patients with unilateral supratentorial stroke.
  • To identify specific white matter pathways affected in stroke patients who aspirate.

Main Methods:

  • Patients were categorized into liquid aspiration (22) and normal swallowing (18) groups post-stroke.
  • Voxel-based lesion-symptom mapping and diffusion tensor imaging (DTI) metrics (FA, MOA, MD) were analyzed.
  • Group comparisons of DTI metrics were performed on voxel-wise maps.

Main Results:

  • No significant differences in lesion location were found between aspiration and normal groups.
  • The aspiration group exhibited increased fractional anisotropy (FA) and mode of anisotropy (MOA) in the right internal capsule (anterior limb and genu).
  • The normal swallowing group showed increased mean diffusivity (MD) in the right superior longitudinal fasciculus.

Conclusions:

  • Right hemisphere internal capsule white matter integrity is associated with aspiration after stroke.
  • Degeneration in specific white matter tracts, like the internal capsule, may predispose stroke survivors to aspiration.
