• A. Thalamus and cerebral cortex of the brain
• B. Thalamus and medulla oblongata
• C. Cerebral cortex and medulla oblongata
• D. None of the above

Answer 1

Answer: (A)

Thalamus and cerebral cortex of the brain

In the vertebrate brain, the thalamus is the midline symmetrical structure between the cerebral cortex and midbrain. Thalamus functions to relay sensory and motor signals to the cerebral cortex besides regulation of sleep and alertness. The cerebral cortex is the outer covering of grey matter over the hemispheres and includes areas or cortices responsible for receiving sensory input and production of voluntary limb or eye movements. So, the correct answer is option A.
