The binding sites of nociceptin (also named orphanin FQ), the endogenous ligand of ORL1 (opiate receptor like 1), were localized in rat brain, using an autoradiographic procedure. High levels of binding were observed in the cingulate, retrosplenial, perirhinal, insular and occipital cortex, anterior and posteromedial cortical amygdaloid nuclei, basolateral amygdaloid nucleus, amygdaloid complex...

The amygdaloid complex is composed of nuclei of various cellular structure, different connections and differentiated functions. Delimi-tation of separate amygdaloid nuclei on the basis of cytoarchitectionic or myeloarchitectonic principles exclusively is very often difficult. Therefore it seems, that in addition to purely morphological methods some histochemical techniques have to be elaborated...

Backgrounds: Crying seizures is a rare type of seizure. Some scholars believe that crying seizures are mainly associated with lesions in the anterior temporal lobe, typically the non-dominant hemisphere, which has close connections with negative emotions. However, the role of amygdaloid lesions in crying seizures is not fully understood. Methods: By a patient with crying seizures and lesions in...

The effect of repetitive administration of naloxone on the development of massed amygdaloid kindling in 'encéphale isolé' cats was studied. Electrical amygdaloid kindling was carried out with a 15 min inter-stimulus interval (ISI) in a control situation with intravenous (i.v.) naloxone administration (2, 4, and 8 mg/kg), 5 min prior to amygdaloid stimulation. It was found that it was possible t...

Amygdaloid cysts are rare cystic benign tumors due to congenital malformations resulting from an anomaly of embryonic development the upper laterocervical region, originating second branchial cleft. They represent approximately 2% all and 6% 85% anomalies This cleft is a frequent reason for consultation in pediatric population but relatively adults. We report cases two patients aged 23 34 years...
