RESUMO
The knowledge of neural plasticity is used to improve motor function of the spinal cord by chronic stimulation of the dorsal columns. We achieved this with an improvised technique. The electrodes are exteriorized and stimulated by using a Grass stimulator. Five paraplegic patients with different aetiologies causing their paraplegia were treated by this method, and the details are enumerated. Four had good improvement and relaxation was maintained for varying periods after cessation of the stimulation. Mode of action is discussed.

During the routine follow-up of results of stereotaxic surgery in the patients treated for behaviour disorders, it was found that some of them had a bonus relief from seizures, Out of 260 amygdalotomies, 54 hypothalamotomies and 5 thalamolaminotomies performed for behavioural problems, 107 patients suffered from associated seizure disorder. 76 of them (71%) showed considerable relief from seizures following surgery. This is detailed. It is hypothesized that probably these nuclei of the "limbic system" either initiate and/or propagate seizure activity. This view is supported by the "improvement" in EEG in addition to the clinical improvement seen in these patients.

The initial suppression of acid secretion in Insulin Test has been a subject of various interpretaitons. A study of hypothalamic recordings in a patient undergoing sedative neurosurgery for behaviour disorders revealed marked suppression of electrical activity in the lateral hypothalamic nucleus within three minutes after the injection of insulin, followed later by spike formation corresponding to parasympathetic stimulation, when hypoglycaemia is established. It appears that the initial suppression of acid secretion is due to a direct action of insulin, suppressing electrical activities of lateral nucleus, the spike formation occurring later, corresponding to onset of hypoglycaemia with stimulation of the nucleus and consequently gastric secretion.
