[The dynamic behavioral changes in rats after destruction of the locus coeruleus].

[Article in Russian]


Destruction of locus coeruleus (LC) was conducted in adult rats (male rats of the Wistar line, 250-300 g) electrolytically or by means of 6-hydroxydopamine (6-OHDA). Behaviour of the intact animals sham-operated and of rats with destructed LC was evaluated before and every week after the operation during 5 weeks. Statistically significant alterations in the behaviour were revealed only in the initially low-active rats. These animals were characterized firstly, by low motor and exploratory activity in all tests (open field and automated devices), disturbance of the reactivity to novelty--only in one week after the operation with subsequent compensation of shifts; secondly, by low level of investigatory activity in the open field and absence of habituation to the repetitive tests--from the 21-st day after the operation.
