Question

BlackTom AI · Accepted Answer

The question asks to identify which statement about Ramon y Cajal is NOT true.
Option 1: 'He received the Nobel Prize for his work in Neuroanatomy in ~1900.' This is inaccurate because Cajal received the Nobel Prize in Physiology or Medicine in 1906, not around 1900. The date is a factual error, making this option false.
Option 2: 'Used silver stain to observe Purkinje cells in the cerebellum.' This aligns with Cajal’s renowned work using Golgi silver staining to reveal detailed morphology of Purkinje cells in the cerebellum, so this statement is true.
Option 3: 'Used silver stain to observe granule cell bodies in the developing optic nerve.' While Cajal employed silver staining to visualize many neuronal elements, including granule-like or granule-cell–type appearances in developing neural contexts, this phrasing fits with his broader demonstrations of neural elements during development. If interpreted as describing observations made with silver staining in developing neural tissue related to optic pathways, it can be considered true within the scope of his developmental neuroanatomy work.
Option 4: 'Used silver stain to observe radial glia in the developing cerebral cortex.' Cajal did describe radial glial processes and their role in development, often illustrated with silver staining and Golgi methods, making this statement true.
Option 5: 'Used silver stain to observe radial glial cells in the developing neural tube.' Cajal’s work extended to early neural tube development and highlighted glial elements; describing radial glial cells in the developing neural tube fits with his developmental observations, so this is true.
In summary, the only statement that clearly conflicts with established historical details is the Nobel Prize date in option 1, which occurred in 1906 rather than ~1900. The other statements describe observations and techniques associated with Cajal’s neuroanatomical work using silver staining or the Golgi method. Therefore, option 1 is the statement not true about Ramon y Cajal.
