ABSTRACT
Eighteen patients were operated upon as follows: in 12 cases bilateral ligation of the superior cerebral veins was carried out as described below; in 2 cases bilateral surgical thalamotomy was performed, an incision being made into the region of the dorso-median nucleus on each side; in 2 cases thermocoagulation of the cerebral cortex in the rostral portion of each frontal lobe was done; while in the 2 remaining cases topectomy procedure was carried out. In one of the latter a prefrontal lobotomy had previously been done, and in the second case a previous cortical ablation. The reasons for doing these various procedures have been presented in Chapter 1.
