The original sentence is: "The brain gets more tired of stress, than of studies." To make it grammatically correct and easy to understand, we can say:
"The brain gets more tired from stress than from studying."
Explanation:
- We say "tired from" when explaining the cause of tiredness.
- We use "than" without a comma before it.
- We use "studying" instead of "studies" to mean the activity of studying.
So, the corrected sentence clearly means that stress makes the brain more tired than studying does.
