“…Third, the origin of the seizure and the spread of the afterdischarge can vary from subject to subject and from time to time (Wieser, 1983). This possibility is supported by experimental studies on gustatory hallucinations during epileptic seizures, showing that these hallucina tions appear only when the afterdischarge propagates to the opercular region (Hausser-Hauw and Bancaud, 1987).…”

ABSTRACT:The authors present a neurobiological model for near-death experiences (NDEs) in an attempt to correlate the biological and psychological domains. This model is based on temporal lobe dysfunction, hypoxialischemia, stress, and neuropeptide/neurotransmitter imbalance. They describe and dis cuss the fundamental contribution of the language system in the construction of verbal reports of NDEs. This model could be seen as a complement to other explanatory domains.The phenomenology of near-death experiences (NDEs) has been de scribed by several authors (Greyson, 1981(Greyson, , 1983a(Greyson, , 1983b(Greyson, , 1985

“…43 Isnard and colleagues also demonstrated that all MTLE seizures invaded the insula, but the site of the discharge onset in the insular was highly variable in individuals, related neither to the discharge pattern nor to the mode of propagation. 4 In the same way, posterior insula is connected to the primary and secondary somatosensitive cortices and the parietal opercula.…”

Somesthetic and emotional symptoms that are common in patients with mesial temporal lobe epilepsy are usually related to hippocampo-amygdalar complex involvement. Recent stereo-electroencephalographic studies have shown a relationship between such symptoms and epileptic insular discharges. To further investigate this problem, we carried out a positron emission tomography study using fluorodeoxyglucose (18F-FDG) and flumazenil (11C-FMZ) in mesial temporal lobe epilepsy patients. The aim of our study was to assess the existence of a cortical insular involvement in order to examine its clinical correlates and the relationship between the postoperative outcome and the insular involvement. Fluorodeoxyglucose and flumazenil-positron emission tomography studies were carried out in 18 patients with mesial temporal lobe epilepsy patients. A statistical parametric mapping (SPM96) was performed to analyze the data in comparison to 18 healthy volunteers. For each set of fluorodeoxyglucose and flumazenil images a group and an individual analysis were performed. In addition, a region of interest analysis was performed to validate the results. Focusing on the metabolic abnormalities, we also investigated the role of insular cortex in the symptoms experienced by the patients and the prognostic value of insular metabolic abnormalities. Highly significant hypometabolism and BZR binding decreases were detected in the insular cortex. Results were similar using the region of interest approach. Insular involvement (mainly ipsilateral to the seizure focus) was present in 60% of the patients. Emotional symptoms correlated with hypometabolism in the anterior part of the ipsilateral insular cortex, whereas somesthetic symptoms correlated with hypometabolism in the posterior part. No relationship between postoperative outcome and ipsilateral insular hypometabolism was found. Unilateral mesial temporal lobe epilepsy is associated with insular hypometabolism and benzodiazepine receptor loss. Our results also suggest that the anterior part of the insular cortex is involved in the emotional symptoms and the posterior insular cortex is involved in the somesthetic symptoms. Hypometabolism located in the insula did not influence postoperative outcome after anterior lobectomy.

“…The weight of the electrophysiological and phenomenological evidence overwhelmingly supports the view that limbic activation contributes to the dyscontrol phenomenon. For example, when stereotaxically implanted depth electrodes in the limbic area are used with dyscontrol clients, abnormal discharges are recorded (Bach-y-Rita et al, 1971;Wieser, 1983). Further, the subjective experience of an altered state of consciousness is widely reported during dyscontrol episodes, described as uncharacteristic of the individual's 'life flow' (Monroe, 1975), and as marked by the release of primitive aggressive behaviours (Elliott, 1982).…”

“…S.-Afr.Tydskr.Siclk.1990,20(4) However, the history of dyscontrol studies is replete with examples of such exclusivity, reflected in the diversity of names given to this disorder. Some descriptors emphasize the supposed biological basis of dyscontrol, such as 'limbic rage' or 'limbic dyscontrol' (Wieser, 1983) or 'dysrhythm tic aggressive behavior disorder' (Hill & Watterson, 1942); others emphasize a supposed psychopathological origin, such as 'impulsive neurosis' or 'criminal sociopathic personality ' (pincus & Tucker, 1974) or 'pseudopsychopathic personality ' (peters, 1983). Other terms, ostensibly neutral, imply an organic pathology, such as 'episodic behavioral dyscontrol' (Monroe, 1970), or 'episodic dyscontrol' (Mark & Ervin, 1970).…”

Rage dyscontrol, defined as rage outbursts that are strikingly disproportionate to the provoking stimulus, ranges in intensity from verbal abuse through to episodes of sufficient violence to cause significant property damage, injury, or death to others. The emergence and current status of rage dyscontrol as a distinct clinical entity are reviewed, a typology of dyscontrol constructed, and its known organic substrates described. The dyscontrol syndrome, shown to be unrelated to temporal lobe epilepsy, is then reviewed in relation to developmental antecedents on the one hand and a known history of traumatic brain injury on the other. Finally, the likely utility of rage dyscontrol as an extenuation in criminal cases is discussed in the light of a case history. The treatment of rage dyscontrol is considered in Part 2 of the article (this issue).Onbeheerste woede, gedefinieer as woede-uitbarstings wat buite verhouding met die veroorsakende stimulus is, wissel in intensiteit van verbale skeltaal tot voorvalle van sodanige gewelddadigheid dat dit kan lei tot saakbeskadiging, of besering of die dood van ander. Die voorkoms en huidige status van onbeheerste woede as 'n onderskeibare kliniese entiteit word oorsigtelik bespreek, 'n tipologie van onbeheerstheid word aangebied, en die bekende organiese substrata daarvan word beskryf. Die onbeheerstheidsindroom, wat in die studie as onverwant aan temporale kwab-epilepsie aangetoon word, word daarna beskou in relasie met ontwikkelingsantesedente aan die een kant en 'n bekende geskiedenis van traumatiese breinbesering aan die ander kant. Laastens word die waarskynlike benutting van onbeheerste woede as versagting in kriminele gevalle in die lig van 'n gevallestudie bespreek. In die tweede deel van hierdie artikel (hierdie uitgawe) word daar ingegaan op die behandeling van onbeheerste woede.
