[Evaluation of the basic characteristics of rat behavior in the "open field" test]. 1981

A L Markel'

Heart rate, motor activity and defecation were studied in rats of the Wistar strain in 10 successive one-hour "open field" tests. Defecation and heart rate parameters decreased monotonously both from test to test and throughout one session. In motor activity a second rise was recorded at 6--12th minutes against the background of a gradual decline. A positive correlation between the total value of defecation and the heart rate in 2nd-3rd minutes of the first test was observed. At the 13th minute the motor activity positively correlated with the heart rate. Significant negative correlation between motor activity and total value of defecation appeared only at 10--11th minutes of the first test. A conclusion is drawn on twofactorial motivational basis of rats' behaviour in the "open field" test.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001341	Autonomic Nervous System	The ENTERIC NERVOUS SYSTEM; PARASYMPATHETIC NERVOUS SYSTEM; and SYMPATHETIC NERVOUS SYSTEM taken together. Generally speaking, the autonomic nervous system regulates the internal environment during both peaceful activity and physical or emotional stress. Autonomic activity is controlled and integrated by the CENTRAL NERVOUS SYSTEM, especially the HYPOTHALAMUS and the SOLITARY NUCLEUS, which receive information relayed from VISCERAL AFFERENTS.
