A researcher is interested in learning more about individual perceptions of pain and develops a trial where participants experience electric shocks. He applies a low grade electric shock to a participant’s right hand. Where would this information typically be processed by the participant’s brain?
- a)Left side of the cerebral cortex
- b)Both sides of the cerebral cortex
- c)Right side of the cerebral cortex
- d)Pain sensation is not processed by cerebral cortex
Correct answer is option 'A'. Can you explain this answer?

The cerebral cortex is the outer layer of the brain responsible for higher cognitive functions, including sensory perception. The cortex is divided into two hemispheres, the left and right hemispheres, with each hemisphere receiving and processing sensory information from the opposite side of the body.
In this scenario, the electric shock applied to the participant's right hand would generate sensory signals that travel through the peripheral nervous system and reach the somatosensory cortex of the brain. The somatosensory cortex, which is located in the parietal lobe, is responsible for processing tactile and sensory information from the body.
Due to the contralateral organization of the brain, the sensory information from the right hand would be processed in the left somatosensory cortex. Therefore, the correct answer is Option A: Left side of the cerebral cortex.

Left side of the cerebral cortex
Electric shock to the right hand would typically be processed by the left side of the cerebral cortex. Here's why:
Contralateral Processing
- The brain processes sensory information from the opposite side of the body, known as contralateral processing.
- This means that sensory input from the right hand would be processed by the left side of the brain.
Somatosensory Cortex
- The specific area of the brain responsible for processing tactile sensations, such as pain, is the somatosensory cortex.
- The somatosensory cortex is located in the parietal lobe of the cerebral cortex.
Left Hemisphere Dominance
- In most individuals, the left hemisphere of the brain is dominant for language and sensory processing.
- Therefore, sensory information from the right hand, including pain sensations from an electric shock, would be processed in the left side of the brain.
Conclusion
- In summary, when a participant experiences an electric shock to their right hand, the information is typically processed by the left side of the cerebral cortex, specifically the somatosensory cortex in the parietal lobe.
