damage to the right cerebral hemisphere is most likely to reduce the ability to
Right hemisphere brain damage Patients with right hemisphere brain damage most commonly have difficulties with attention, perception, learning, memory, recognition and expression of emotion, and neglect.[3] Other frequently occurring, though slightly less common, deficits include reasoning and problem solving, awareness, and orientation.[3] It is also common for patients with right hemisphere damage to have a flat affect, lack of emotional expression, while speaking. Additionally, these patients commonly have difficulty recognizing other people's emotions when expressed through facial expressions and tone of voice.[2] Although these deficits alone may complicate therapy, the patient may also exhibit anosognosia, or ignorance of his or her impairments.[4][5] Due to possible anosognosia, it is common for patients to not become frustrated or upset when they are unable to complete tasks they were previously able to complete.[6]
Visual cortex Both hemispheres of the brain contain a visual cortex; the visual cortex in the left hemisphere receives signals from the right visual field, and the visual cortex in the right hemisphere receives signals from the left visual field.
