Which lobe lesion is associated with visual loss and perceptual deficits such as visual agnosia?

A lesion in the occipital lobe is associated with visual loss and perceptual deficits, including visual agnosia. The occipital lobe is primarily responsible for processing visual information received from the eyes. When there is damage or a lesion in this area, it can lead to significant disruptions in visual perception, including the inability to recognize visual stimuli, which is known as visual agnosia.

Visual agnosia occurs when the brain has difficulty interpreting visual information, even though the individual may have intact vision. This can affect the ability to recognize objects, faces, or specific visual features. In contrast, lesions in the frontal lobe typically result in changes in personality, planning, and motor functions, the parietal lobe may affect sensory integration and spatial awareness, and the temporal lobe is chiefly involved in auditory processing and memory. Therefore, the occipital lobe's role in visual processing makes it the correct response for visual loss and perceptual deficits like visual agnosia.
