The period is defined by the fusion of experimental manipulation, clinical observation, and pathological analysis to decode nervous system diseases. Researchers forged links between induced neurophysiological changes and patient manifestations, especially in hydrocephalus, where cerebrospinal fluid dynamics were mapped to ventricular enlargement and brain pathology. The approach broadened to demyelinating and nutritional neuropathology, emphasizing underlying patterns over isolated lesions and promoting early evidence-based correlations within neuropathology.
