I don't think you mean above the medula oblongata, i think you mean something else because the connection between the two hemispheres is connected by the Corpus Callosum which is above of the thalamus.
The only answer that i can make sense of what you've wrote is A Cerebellum but i don't think you are correct forming your question. Where did you find the question
Explanation:
Isotonic contractions generate force by changing the length of the muscle and can be concentric contractions or eccentric contractions. A concentric contraction causes muscles to shorten, thereby generating force. Eccentric contractions cause muscles to elongate in response to a greater opposing force.
The correct answer is the first option - occipital lobe.
The occipital lobe is a part of your brain which is governs your sight and all your visual activities. It got its name from Latin, because ob means behind, and caput means head, so this lobe is located in the back of your brain.
