Final answer:
After damage to the brain's visual cortex, people can experience various visual impairments, such as cortical blindness or problems with color perception.
Step-by-step explanation:
When the brain's visual cortex is damaged due to stroke or surgery, people often report experiences such as an inability to see, loss of visual field, or visual distortions. The visual cortex is responsible for processing visual information, so any damage to this area can result in various visual impairments.
For example, when the primary visual cortex is damaged, a person may experience cortical blindness, which means they are unable to see anything in their visual field. Damage to other parts of the visual cortex can result in specific visual deficits, such as problems with color perception or recognizing faces.
It is important to note that the specific experiences and symptoms vary depending on the location and extent of the damage to the visual cortex. Rehabilitation and visual therapy can help individuals adapt and regain some visual function.
