Question

Which function will be lost if the occipital lobe is damaged?
A. Hearing
B. Speech
C. Vision
D. Memory

Answer 1

Hint: The human brain is composed of four different lobes: frontal, parietal, temporal, and occipital. The main functions that are performed by each of them are control of movements, taste, touch, sight, and memories respectively.

Complete Answer:
Each side of the human brain consists of four lobes. The frontal lobe is required for cognitive functions and control of voluntary movements. The parietal lobe helps to transform information about surroundings like temperature, taste, touch, and movement, and the. The occipital lobe has originated its name from its location. It is located below the occipital bone of the skull. It is the smallest of all the four lobes that is observed in the brain.

Now let us find solution from given options
- Hearing: The temporal lobe receives signals from the external ear and provides information about hearing and processing the sound.
- Speech: Temporal lobe also performs the functions of speech.
- Vision: Occipital lobe is primarily involved in the role for vision
- Memory: The temporal lobe is responsible for the processing of memories and integrating them with sensations of taste, sound, sight, and touch.

Hence the required option is C that is vision.

Note: The optic lobes are observed in the brains of many animal species. The optic lobe of arthropods is a part of the protocerebrum that is located behind the arthropod eye and is responsible for the processing of visual information for the organism. The optic lobes of a bird or reptile are also a structure of the midbrain. The birds show the best vision as compared to any other vertebrate.
