PSYB57H3 Lecture Notes - Lecture 5: Sensory Memory, Motor Cortex, Classic Case
Both hemispheres contribute to controlled attention, both the left and the right hemisphere, but the right hemisphere is more important. Most injured patients impairments were always more severe if the damage was to the right hemisphere. If you disrupt the right hemisphere due to a stroke, a brain injury or a neurological disorder, this will affect your ability to pay attention. If you suffer a stroke, the majority of the time the impairment is usually on the right side of the brain. Hemisphere neglect is where half of space that is destroyed, most of the time it is the left side of space. This is an impairment of attention or conscious awareness to the left side of space caused by brain injury. There are cases of people no longer recognizing the left side of the body. The is a neurologically impairment of attention, not vision. This is as common as an impairment to language after a stroke.
