Patients with a paralyzed limb may experience a supernumerary phantom limb due to brain lesions. This illusion arises from intact motor intent despite ineffective movement, causing a stable phantom sensation.

Area of Science:

  • Neuroscience
  • Neurology
  • Motor Control

Background:

  • Investigating a novel form of chronic supernumerary phantom limb.
  • Understanding its association with motor intent in hemiplegic-anesthetic limbs.

Observation:

  • The phantom limb illusion occurred with attempts to move the paretic limb, bimanual actions, and motor imagery.
  • A brain lesion in the internal capsule's posterior part was identified as the cause.
  • fMRI revealed increased thalamus and caudate nucleus activation during virtual phantom limb movement.

Findings:

  • The illusion stems from intact premotor processes translating intention into action, creating a sense of agency.
  • Interrupted thalamic afferences may stabilize the phantom by preventing error correction.

  • Abnormal basal ganglia-thalamus-cortex pathway functioning underlies the phenomenon.

    • Implications:

    • This study sheds light on the neural mechanisms of phantom limb phenomena.
    • Findings contribute to understanding the interplay between motor intent, agency, and sensory illusions.
    • Potential insights for managing phantom limb sensations and related neurological conditions.
