1900-1901

Cushing begins operating for relief of trigeminal neuralgia (extirpation of Gasserian ganglion) (Fulton, 262-66). Cushing travels to Europe, meets Horsley (Thomson, 94-96; Fulton, 163, 167-168); he also met Sherrington, for whom he surgically exposed anthropoid brains (Thomas, 110; Fulton, 195-200); spends time in Berne, working in Physiological Laboratory (“Hallerianum”) under Kronecker and Kocher (Thomson, 100-106; Fulton, 176ff, 182-184). For Kocher, he studied effect of pressure in brain on circulation/respiration. Cushing saw Kocher as much like Halsted and, apropos Kocher’s clinic, remarked: “—but the operating!! -- the J.H.H. outdone” (Fulton, 177). Cushing the only pupil whom Kocher asked to operate (Fulton, 182). Cushing socialized in Bern with Hughlings Jackson. In fall of 1901, Cushing returns to Hopkins and works out arrangement with Halsted to remain at Hopkins, taking over the neurological side of the surgical clinic (113) (Thompson, 94ff.).
