Ictal behavioral characteristics may provide clues in determining the nature of the epileptic focus. We defined ictal behavioral characteristics in patients with intractable temporal lobe epilepsy (TLE) who underwent anterior temporal lobectomy (ATL) and lived seizure-free for 2 years of follow-up. Video/EEG data on 282 seizures observed in 48 patients who suffered from TLE and underwent ATL were analyzed. All patients were seizure-free after surgery. We divided the patients into two groups on the basis of the pathological examination. Two hundred and two seizures in 35 patients with hippocampal sclerosis (Group 1) and eighty seizures in 13 patients with other pathological findings, such as tumors, cavernoma, and hamartoma (Group 2), were analyzed. Ictal behavior characteristics were evaluated for each of the seizures recorded in the two groups. Behavioral arrest, bilateral hand automatisms, oral and leg automatisms, and ictal aggression were significantly more frequent in Group 2 (P<0.05), whereas contralateral dystonia of the upper extremity (P<0.05), ipsilateral hand automatisms (P<0.05), ipsilateral hand automatisms in the presence of contralateral dystonia of the upper extremity (P<0.001), contralateral forced head deviation (P<0.05), and secondary generalization (P<0.05) were more significant in Group 1. There was no significant difference in vocalization and ipsilateral nonforced head deviation between the two groups (P>0.05). The number of seizures observed during ictal speech, crying, and postictal nose wiping was not large enough, so differences could not be analyzed. It was concluded that although ictal behavioral characteristics differed between the two groups, certain behavioral patterns may be helpful in differentiating between hippocampal sclerosis and other pathology.

Advances in functional neurosurgery, including neuromodulation and more recently ultrasonic ablation of basal ganglia structures, have improved the quality of life for patients with debilitating movement disorders. What is little known, however, is that both of these neurosurgical advances, which remain on the cutting edge, have their origin in the pioneering work of Russell Meyers, whose contributions are documented in this paper. Meyers' published work and professional correspondence are reviewed, in addition to documents held by the Department of Neurosurgery at the University of Iowa. Meyers was born in Brooklyn, New York, and received his neurosurgical training at hospitals in New York City under Jefferson Browder. In 1939, a chance encounter with a young woman with damaged bilateral ventral striata convinced Meyers that the caudate could be resected to treat Parkinsonism without disrupting consciousness. Shortly thereafter, he performed the first caudate resection for postencephalitic Parkinsonism. In 1946, Meyers became the first chairman of neurosurgery at the State University of Iowa (now the University of Iowa), which led to the recruitment of 8 faculty members and the training of 18 residents during his tenure (1946-1963). Through collaboration with the Fry brothers at the University of Illinois, Meyers performed the first stereotactic ultrasonic ablations of deep brain structures to treat tremor, choreoathetosis, dystonia, intractable pain, and hypothalamic hamartoma. Meyers left academic neurosurgery in 1963 for reasons that are unclear, but he continued clinical neurosurgery work for several more years. Despite his early departure from academic medicine, Meyers' contributions to functional neurosurgery provided a lasting legacy that has improved the lives of many patients with movement disorders.
