Summary
Motor impersistence, a neurological condition, is more common after right brain damage. This case study highlights increased motor impersistence in the right limb following a specific brain lesion, demonstrating hemispatial neglect effects.
Area of Science:
- Neuroscience
- Neurology
- Clinical Neuropsychology
Background:
- Motor impersistence is observed more frequently following right hemispheric lesions compared to left.
- Lesions involving the corpus callosum can lead to motor impersistence, potentially affecting the dominant limb more severely.
Observation:
- A 66-year-old right-handed male patient presented with motor impersistence in the right limb.
- The patient had a history of infarction in the right medial frontal lobe and corpus callosum.
Findings:
- Bedside evaluation and experimental testing confirmed right limb motor impersistence.
- Results indicated hemispatial effects, with more pronounced impersistence observed in the neglected right-sided space.
Implications:
- This case provides evidence for the lateralization of motor impersistence and its association with visuospatial neglect.
- Understanding these hemispatial effects is crucial for diagnosing and managing neurological deficits after focal brain injuries.

01:28Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
01:28Lateralization
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.
01:33Somatosensation
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.
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
