В селектируемой линии появляются новые поведенческие формы, отличающиеся от отбираемых форм по селекционному критерию. В линии ГК (генетическая кататония) в большом количестве стали рождаться «нервные» крысы. Селекционный критерий предполагает отбор по признаку длительного каталептического застывания, однако «нервные» особи характеризуются повышенным уровнем моторной возбудимости: побежками, прыжками и вокализацией. Основной целью настоящей работы было определение фенотипических параметров у крыс линии ГК и выделение главных компонент изменчивости по эмоциональным и весовым показателям. Контролем служили крысы из исходной популяции Вистар. Измеряли время каталептического застывания, уровень возбудимости животных, артериальное давление, акустический рефлекс вздрагивания, судорожную активность, массу сердца, почек, надпочечников, селезенки. Применяли методы многомерного анализа: факторный анализ и метод главных компонент. В исследуемом поколении крыс ГК подтверждена склонность к застыванию в спокойной обстановке и после действия  сильного аудиогенного раздражителя, отмечены более интенсивные реакции вздрагивания, умеренная гипертония, более высокий относительный вес сердца и надпочечников. Выделены две основные компоненты изменчивости: амплитуда вздрагивания (РС1) и морфофункциональная изменчивость (РС2). Определено различное расположение точек у особей Вистар и ГК в координатах первых главных компонент. Получено подтверждение  генетического единства реакций застывания и «нервности» с помощью метода главных компонент. Показано, что в РС2 абсолютные показатели массы сердца, почек, надпочечников и селезенки вносят отрицательный вклад при положительных значениях таких показателей, как застывание и «нервность». В этой же компоненте отмечено усиление реакций застывания и «нервности» при положительной корреляции с относительной массой сердца и надпочечников. Обсуждаются различия по знакам вкладов во вторую компоненту морфофункциональной изменчивости.</p></abstract><trans-abstract xml:lang="en"><p>In selecting rats for behavior, we observe a direct natural effect and affect the nonspecific stress function. In this process, new behavioral phenotypes appear in the strain under selection. They differ from the selected forms in the selection criterion. In the GC strain, a large proportion of the so-called nervous rats emerge. The criterion presumes the selection for the long cataleptic freezing character, whereas the nervous rats display elevated motor excitement: running, jumping, and vocalization. The main purpose of our study was to assess phenotypic indices in GC rats (abbreviated from genetic and catatonia) and recognize principal components of variability for emotional and weight indices. Rats of the ancestral Wistar population were taken as control. The following indices were measured: time of cataleptic freezing, excitement level, blood pressure, acoustic startle response, seizure  activity, and weights of the heart, kidneys, adrenals, and spleen. Multivariate analysis methods were applied: factor analysis and principal component analysis. We confirmed the inclination of GC rats of the generation studied to freezing in quiet surrounding and after a strong acoustic sti - mulus. More pronounced startle responses,  moderate hypertension, and larger weights of the heart and adrenals were noted. Two principal variability components were recognized: startle amplitude (PC1) and morphofunctional variability (PC2). The figure shows different locations of Wistar and GC individuals in principal component coordinates. The principal component method confirmed the genetic relationship between the startle and nervousness responses. It was shown that in PC2 the indices of heart, kidney, adrenal, and spleen weight exert negative effects, whereas the effects of startle and nervousness were positive. In the same component, an increase in the startle and nervousness responses positively correlates with the relative weights of the heart and adrenals. Differences in the directions of the contributions to the second component of morphofunctional variability are discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модель кататонии</kwd><kwd>селекция</kwd><kwd>рефлекс вздрагивания</kwd><kwd>артериальное давление</kwd><kwd>эпилепсия</kwd><kwd>вес органов</kwd><kwd>многомерный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>model of catatonia</kwd><kwd>selection</kwd><kwd>startle-reflex</kwd><kwd>arterial pressure</kwd><kwd>epilepsy</kwd><kwd>organ weights</kwd><kwd>multidimensional analysis</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>State Budgeted Project 03242018­0016; Russian Foundation for Basic Research, project 17­04­01631; equipment of the Shared Access Center was supported by the Russian Ministry of Education and Science, project RFMEFI62117X0015; Institute of Cytology and Genetics (Novosibirsk) Dr. Sci.
