Summary
Right hemisphere brain injury causes visuospatial neglect. White matter integrity and inter-hemispheric connectivity influence recovery by enabling brain plasticity and compensatory activity.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Neurology
Background:
- Visuospatial neglect is a common deficit following right hemisphere brain injury.
- It involves impaired attention to left-sided stimuli due to fronto-parietal network dysfunction.
- Brain networks can reorganize post-injury, with outcomes ranging from recovery to chronicity.
Purpose of the Study:
- To explore factors influencing the recovery or chronicity of visuospatial neglect.
- To highlight mechanisms constraining the temporal and spatial aspects of neglect evolution.
- To investigate the role of brain plasticity and connectivity in neglect.
Main Methods:
- Review of existing literature on visuospatial neglect and brain plasticity.
- Analysis of potential trajectories of network reorganization after unilateral brain injury.
- Examination of the impact of white matter integrity and inter-hemispheric connectivity.
Main Results:
- White matter pathways are crucial for compensatory brain plasticity.
- Inter-hemispheric connectivity is critical for shifting the left hemisphere's role from maladaptive to compensatory.
- Connectivity constraints influence the evolution of neglect.
Conclusions:
- The integrity of white matter pathways and inter-hemispheric connections are key factors in visuospatial neglect recovery.
- Brain plasticity's effectiveness is modulated by the brain's structural connectivity.
- Understanding these mechanisms can inform interventions for neglect.

01:28Lateralization
647
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.

01:12Visual Agnosia
471
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...

01:05Cerebral Hemispheres
1.1K
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...

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...

01:21Association Areas of the Cortex
6.9K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

01:22Lobes of the Cerebrum
2.2K
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....
