Final answer:
Electroencephalography (EEG), Positron emission tomography (PET), and functional magnetic resonance imaging (fMRI) would have been available to doctors for monitoring brain activity in 1932.
Explanation:
EEG, PET, and fMRI would have been available to a doctor practicing in 1932 as neuroimaging methods to monitor brain activity. Electroencephalography (EEG) measures the brain's electrical activity with high temporal resolution; PET uses positron-emitting tracer atoms to create 3D images of brain metabolic needs; fMRI creates images of brain activity using a magnetic field.
