Answer: Positron Emission Tomography (PET)
Explanation: A Positron Emission Tomography (PET) scan can be simply referred to as an imaging test that helps to tell or show doctors how how organs or tissues are functioning. This test involves the uses of special dyes which is made up of radioactive tracers, they are either injected or inhaled by patient depending on the organ which the test is to be carried out on.
So the next best technique Veda could use as she doesn't have access to an fMRI machine is the Positron Emission Tomography (PET).
Using this technique, the PET scanner can trace the special dyes contain radioactive tracer as they are more concentrated on areas or part of the organs with high chemical activities, this could help her get information about brain activity during the card task.
This is of course a very complex question that does not have a definitive answer, but 1850s would be a good decade to start counting as "Modern". This was a decade of the telegraph and Darwin's The Origin of Species.
