Cerebral Hemispheres01:05

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Cerebrum: Anatomical Overview II

Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...
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.
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"...
Pleiotropy01:33

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
Alzheimer Disease ll: Pathophysiology01:23

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Area of Science:

  • Neuroimaging
  • Neurology
  • Radiology

Background:

  • Neurological Wilson's disease (WD) typically affects basal ganglia and thalamus.
  • Corpus callosum (CC) lesions in WD have not been extensively studied.
  • This study investigates the prevalence and significance of CC lesions in WD.

Purpose of the Study:

  • To determine the frequency of corpus callosum (CC) lesions in neurologically symptomatic Wilson's disease (WD) patients.
  • To correlate CC lesions with clinical disability.
  • To assess the diagnostic value of CC lesions in WD.

Main Methods:

  • Retrospective analysis of brain MRIs from 81 neurologically symptomatic WD patients (2006-2008).
  • Evaluation of lesion localization, focusing on the corpus callosum (CC).
  • Assessment of clinical disability using the Unified Wilson's Disease Rating Scale.

Main Results:

  • 42% of patients showed white-matter lesions on MRI.
  • 23.4% of patients had corpus callosum (CC) lesions, primarily in the splenium.
  • Increased disability severity correlated with the presence of CC lesions.

Conclusions:

  • Corpus callosum (CC) abnormalities are relatively common in neurological Wilson's disease (WD), occurring in 23.4% of cases.
  • CC signal changes, alongside basal ganglia lesions, can aid in diagnosing WD.
  • These findings highlight the importance of evaluating the CC in WD patients.
