Summary
Apraxias are subtle motor disorders affecting movement organization, primarily in the left hemisphere. This review details their historical description and classification by pioneers like Jackson and Liepmann.
Area of Science:
- Neurology
- Neuroscience
- Clinical Psychology
Background:
- Apraxias, subtle motor disorders disrupting movement organization, were first described by John Hughlings Jackson in 1861.
- Hugo Karl Liepmann further elucidated apraxias, categorizing them into ideomotor, limb-kinetic, and ideational types based on distinct cortical associational areas.
Discussion:
- Liepmann's classifications highlight specific central nervous system pathways involved in motor planning and execution.
- The concept of 'disconnection syndromes' by Geschwind later expanded the understanding of apraxias, linking them to disruptions in neural communication.
Key Insights:
- Apraxias represent a significant category of motor dysfunction with a well-documented historical progression of understanding.
- Distinguishing between different apraxia types is crucial for localizing neurological lesions and understanding cognitive-motor integration.
Outlook:
- Further research can refine the understanding of the neural underpinnings of various apraxias.
- Investigating the impact of apraxias on daily functioning and developing targeted interventions remains an important clinical goal.

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...

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"...
01:33Somatosensation
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.
01:24Prosopagnosia
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...
01:28Lateralization
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.
