Which of the following statements about medieval beliefs links memory loss to brain region function?

• A. It was thought to depend on the balance of moisture and temperature of the third ventricle
• B. It was attributed to the hippocampus
• C. It was linked to the pineal gland
• D. It was attributed to the spinal cord

Answer: (A)

In medieval thought, brain function and memory were explained through humoral theory and the idea that mental faculties depend on the fluids and heat within the brain’s spaces. The statement that memory loss was due to the balance of moisture and temperature in the third ventricle fits this framework, since it locates memory and its disruption to a central brain region governed by fluid balance and warmth. This reflects how ancient and medieval scholars imagined the brain as a system of ventricles filled with vital fluids whose state could influence recall.

The other ideas belong to later periods or different theories. Identifying memory with the hippocampus is a modern discovery tied to detailed neuroanatomy, not medieval belief. The pineal gland as the memory center or switchboard of the mind is more associated with Descartes and early modern philosophy. Linking memory to the spinal cord does not align with medieval explanations of cognitive function.
