It has been found with MRI imaging that adenoma increasing for 5 years (meantime) in children, then the brain volume is lower, and there is enlargement of the celiac system and atrophia of the amygdaloid nuclei.
In the adult rat, a high density of OT receptors is found in the dorsal peduncular cortex, the anterior olfactory nucleus, the islands of Calleja and ventral pallidum cell groups, the limbic system (bed nucleus of the stria terminalis, central amygdaloid nucleus, ventral subiculum), and the hypothalamic ventromedial nucleus [2,32].
Deficits in amygdaloid CAMP-responsive element-binding protein signaling play a role in genetic predisposition to anxiety and alcoholism.
Because the shorter amygdaloid pathway transmits signals more than twice as fast as the neocortex route, the thinking brain often cannot intervene in time to stop emotional responses (Greenberg, 2002, p.
Besides a small number of supposed amber scarabs from the Eighteenth Dynasty (Hood 1993: 230) and an amygdaloid engraved amber seal from Mycenae (Hughes-Brock 1993:221), the only examples of figurative amber artefacts are two allegedly Neo-Assyrian statuettes of unknown provenance and highly disputed authenticity (Muscarella 2000: 177-8; Beck 1979) and a small lion figurine from Akhziv (Todd 1985: 293), probably dating to the ninth century BC.
New findings by Terenzi and Ingram (55) seem to support this in the following way: in rat central and medial amygdaloid nuclei, administration of OT first increases firing rate, but when repeated, leads to receptor desensitization.
