Summary

Patients with neglect exhibit a tilted body midline representation, with both head and trunk showing a counterclockwise subjective straight-ahead (SSA) tilt and an ipsilesional lateral shift. This spatial bias is more pronounced in the trunk than the head.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Clinical Neurology

Background:

  • Spatial awareness and body representation are crucial for navigation and interaction.
  • Neglect, a disorder of spatial awareness, often affects the representation of the body midline.
  • Understanding the precise nature of body midline distortion in neglect is vital for rehabilitation.

Purpose of the Study:

  • To investigate the subjective straight-ahead (SSA) projection of head and trunk in patients with neglect.
  • To differentiate between lateral shift and lateral tilt components of spatial bias in neglect.
  • To determine if neglect affects the body midline representation as a whole or specific body parts.

Main Methods:

  • Utilized a novel method to disentangle lateral shift and lateral tilt in SSA judgments.

Related Experiment Videos

  • Assessed SSA for head and trunk in patients with neglect and non-neglect controls.
  • Quantified the direction and magnitude of spatial biases for each body part.

    • Main Results:

    • Patients with neglect demonstrated a consistent counterclockwise SSA tilt for both head and trunk.
    • An ipsilesional lateral shift was observed, being more severe for the trunk than the head.
    • Non-neglect patients did not exhibit these significant spatial biases.

    Conclusions:

    • Neglect is characterized by a tilted representation of the body midline, affecting both head and trunk.
    • The observed tilt suggests a fundamental disruption in the internal spatial framework in neglect.
    • These findings have implications for understanding the neural basis of body representation and spatial awareness.
