Abstract: | Characteristics of orienting behavior of intact and handled female white rats were studied in the "open field" test. Experimental group of animals were formed according to stages of estrous cycle: (1) diestrus, (2) proestrus, (3) estrus, and (4) metestrus. The stage of the cycle was determined by vaginal smears. Over the period of 10 days rats were handled daily for 5 minutes. No behavioral changes over the course of estrous cycle were found in intact rats. Handling revealed some behavioral features related to the levels of steroid hormones in reproductive cycle. Most prominent changes in orienting behavior were observed at transition from estrous to metestrous. At the stage of estrous motor activity was maximal and grooming was minimal. The maximal contrast in the structure of orienting behavior was observed between estrous and diestrous stages. |
