PG - 3017-20 AB - THIS study aimed at investigating putative neural substrates of attention-deficit hyperactivity disorder in children using the spontaneously hypertensive rat (SHR) as animal model and the Ca2+/calmodulin-dependent protein kinase II (CaMKII) as a marker in the nucleus accumbens, an interface between limbic and motor systems. In prehypertensive male SHR and Wistar-Kyoto rats image analysis of CaMKII immunocytochemistry showed more positive elements in the shell than in the core, and in the former a lower level in SHR. The data indicate a reduced number of nucleus accumbens modules available for limbic-motor integration revealing putative substrates of the altered attentional and reinforcement mechanisms demonstrated in the SHR and in children with attention-deficit hyperactivity disorder.
