Which function will be lost due to damage of occipital lobe ?

Options

A. Hearing
B. Speech
C. Vision
D. Memory

Answer

### Step-by-Step Solution

1. **Identify the Occipital Lobe**: The occipital lobe is one of the four main lobes of the cerebral cortex in the brain. It is located at the back of the brain and is primarily responsible for processing visual information.

2. **Understand the Functions of Different Lobes**:
- **Frontal Lobe**: Involved in reasoning, planning, problem-solving, emotional regulation, and motor function.
- **Temporal Lobe**: Responsible for hearing, speech, and memory.
- **Parietal Lobe**: Processes sensory information such as touch, temperature, and pain.
- **Occipital Lobe**: Primarily responsible for vision.

3. **Analyze the Options Given**:
- **Hearing**: This function is associated with the temporal lobe.
- **Speech**: This function is also controlled by the temporal lobe.
- **Vision**: This function is primarily managed by the occipital lobe.
- **Memory**: This function is linked to the temporal lobe.

4. **Determine the Impact of Damage to the Occipital Lobe**: If the occipital lobe is damaged, the primary visual area is affected, leading to potential vision loss or disturbances such as hallucinations.

5. **Select the Correct Answer**: Based on the analysis, the function that will be lost due to damage to the occipital lobe is **vision**. Therefore, the correct answer is **option C: vision**.
