How much do you know about hemispatial neglect?

¿Qué es la negligencia?

¿Qué hemisferio controla la atención al hemiespacio opuesto?

¿Qué hemisferio controla la atención al espacio hemisférico opuesto?

¿Qué teoría propuso Kinsbourne para explicar la rivalidad entre los hemisferios?

¿Qué sucede cuando hay daño en el hemisferio derecho?

Negligence is a lack of attention.
The asymmetry in how the two brain hemispheres pay attention to external space can cause negligence.
The left hemisphere controls attention to the opposite right hemispace, while the right hemisphere can orient attention to both left and right hemispaces.
Damage to the left hemisphere doesn't have a significant impact as the intact right hemisphere can attend to both hemispaces.
Damage to the right hemisphere leaves the left hemisphere in charge of attending to the right hemispace only, resulting in neglect of the left hemispace.
Each hemisphere tries to inhibit the other, resulting in rivalry.
Damage to the left hemisphere reduces inhibition of the right hemisphere, allowing it to continue attending to both hemispaces.
Damage to the right hemisphere eliminates attention to both hemispaces and inhibition of the left hemisphere, resulting in reinforced focus on the right hemispace and neglect of the left hemispace.
Heilman and van den Abell observed differences in response between the left and right parietal lobes.
Kinsbourne proposed the inhibition theory to explain the rivalry between the hemispheres.

Test your knowledge on hemispatial neglect, a condition where an individual fails to attend to one side of their body or environment. Learn about the causes and effects of hemispatial neglect, including how the two brain hemispheres interact and compete for attention. This quiz will challenge your understanding of hemispatial neglect, including theories proposed by Heilman, van den Abell, and Kinsbourne.
