Summary
This study describes ipsilateral hyperschematia, a rare size distortion disorder. A patient with a right frontal lesion experienced object enlargement on one side, independent of spatial neglect.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Perception Research
Background:
- Size distortion disorders are rare neurological conditions.
- Understanding spatial perception is crucial for cognitive neuroscience.
- Frontal lobe lesions can cause diverse behavioral and perceptual deficits.
Observation:
- A case study of a woman with a right frontal lesion.
- The patient exhibited ipsilateral hyperschematia, a size distortion disorder.
- This condition occurred without spatial neglect or frontal perseveration.
Findings:
- The patient perceived disproportionate enlargement of objects on the right side of space.
- Drawing tasks revealed an exaggeration of left-sided elements (e.g., daisy petals).
- This demonstrates a specific spatial component in object size perception.
Implications:
- Suggests a distinct neural basis for spatial perception of object size.
- Highlights a specific sub-component of space distortion in the brain.
- Informs future research on body schema and spatial representation disorders.

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.
01:05Cerebral 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...
01:12Visual 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"...
01:24Prosopagnosia
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...
01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
