Предварительно популяция мышей была разделена на субпопуляции по величине индекса внимания особей к незнакомым объектам в отсеках лабиринта – высоковнимательных (ED-high) и низковнимательных (ED-low). Установлено, что фенотропил повышал индекс внимания у ED-low, однако ухудшал его в субпопуляции ED-high, а также изменял показатели тревожности и двигательной активности, что отличало его от более селективного эффекта пирацетама (200 мг/кг/сутки). Большая избирательность пирацетама отражалась и в отношении метаболизма дофамина в ткани префронтальной коры мозга: препарат нормализовал метаболический оборот как внутриклеточного (ДОФУК/ДА), так и внеклеточного (ГВК/ДА) дофамина, тогда как фенотропил корригировал лишь первый. Таким образом, положительное влияние пирацетама на индекс внимания у мышей ED-low соответствует нормализации обоих показателей метаболизма дофамина в префронтальной коре, а фенотропил проявлял неизбирательность как в отношении поведенческих, так и нейрохимических параметров. Оба препарата практически не затрагивали метаболизм серотонина как в коре, так и в стриатумах мышей обеих субпопуляций.</p></abstract><trans-abstract xml:lang="en"><p>The effect of subchronic administration of the nootropics Phenotropil (100 mg/kg/day) on the behavior of CD-1 outbreed mice in the "closed enriched cross maze" test (CECM) was studied. Predominantly, the mouse population was divided into subpopulations according to their values of individual attention index for novel objects in the maze compartments – highly attentive (ED-high) and low attentive (ED-low). It was found that Phenotropil increased the attention index in ED-low, but disimproved it in the ED-high subpopulation, and also changed parameteres of anxiety and locomotor activity; this distinguished it from the more selective effect of Piracetam (200 mg/kg/day). The higher selectivity of Piracetam was also shown in relation to dopamine metabolism processes in the prefrontal cortex: the drug normalized the metabolic turnover of intracellular (DOPAC/DA) as well as extracellular (HVA/DA) dopamine, while Phenotropil influenced on the former only. Thus, positive effect of Piracetam on the attention level in ED-low mice corresponds to the normalization of both indicators of dopamine metabolism in the prefrontal cortex, while Phenotropil showed non-selectivity onto both behavioral and neurochemical parameters. Piracetam and Phenotropil failed to affect the cortical and striatal serotonin metabolism in both subpopulations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пирацетам</kwd><kwd>фенотропил</kwd><kwd>дефицит внимания</kwd><kwd>дофамин</kwd><kwd>серотонин</kwd><kwd>метаболиты</kwd><kwd>префронтальная кора</kwd><kwd>стриатум</kwd><kwd>мыши CD-1</kwd><kwd>ВЭЖХ/ЭД</kwd></kwd-group><kwd-group xml:lang="en"><kwd>piracetam</kwd><kwd>phenotropil</kwd><kwd>attention deficit</kwd><kwd>dopamine</kwd><kwd>serotonin</kwd><kwd>metabolites</kwd><kwd>prefrontal cortex</kwd><kwd>striatum</kwd><kwd>CD-1 mice</kwd><kwd>HPLC/ED</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pennington BF, Ozonoff S.
