Visual Agnosia01:12

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
Prosopagnosia01:24

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
Lateralization01:28

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
Somatosensation01:33

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Summary

Spatial neglect, a heterogeneous condition, shows distinct anatomical correlates for core and satellite symptoms. Right hemisphere perisylvian damage causes gaze bias and unawareness, while posterior injury leads to object-centered deficits.

Area of Science:

  • Neuroscience
  • Neurology
  • Cognitive Psychology

Background:

  • Spatial neglect is characterized by a heterogeneous collection of symptoms.
  • Its anatomical correlates have been controversial, lacking a clear framework.
  • A distinction between core and satellite symptoms offers a new perspective.

Purpose of the Study:

  • To review the literature on spatial neglect through the lens of core and satellite symptom syndromes.
  • To identify clear patterns of anatomical injury associated with specific spatial neglect symptoms.
  • To provide a framework for parsing spatial and attentional syndromes resulting from right hemisphere injury.

Main Methods:

  • Literature review focusing on syndromes of spatial neglect.
  • Correlation of specific symptoms with anatomical brain injury locations.

  • Analysis of acute vs. chronic injury and functional vs. structural imaging modalities.

    • Main Results:

    • Combined symptoms of biased gaze and search with unawareness correlate with right hemisphere perisylvian damage.
    • Object-centered deficits, like line bisection bias, are linked to more posterior and inferior brain injury.
    • Extinction is associated with damage to the temporo-parietal junction.

    Conclusions:

    • A clear pattern of anatomical injury underlies distinct spatial neglect syndromes.
    • Understanding these patterns aids in diagnosing and potentially treating spatial neglect.
    • Differentiating spatial and attentional syndromes requires careful consideration of injury location and type.
