Statistical methods were used to study types of background activity (BA) of neostriatum neurons. Dependence of the crosscorrelation function on the BA type and on a distance between the neurons was examined in acute experiments on rats (one group was immobilized with d-tubocurarin, the other was under nembutal anesthesia). It is shown that BA according to the shape of the autocorrelation and crosscorrelation functions can be classified into five types (I.1, I.2, I.3, II.1, II.2). Pronounced differences in the crosscorrelation function were found between the neurons with grouped BA (I.1, I.2) and the neurons with unitary BA (II.1, II.2). Differences in the crosscorrelation function between close and distant (300-500) microns) neurons were also found.

UI MeSH Term Description Entries
D007103 Immobilization The restriction of the MOVEMENT of whole or part of the body by physical means (RESTRAINT, PHYSICAL) or chemically by ANALGESIA, or the use of TRANQUILIZING AGENTS or NEUROMUSCULAR NONDEPOLARIZING AGENTS. It includes experimental protocols used to evaluate the physiologic effects of immobility. Hypokinesia, Experimental,Experimental Hypokinesia,Experimental Hypokinesias,Hypokinesias, Experimental

D010424 Pentobarbital A short-acting barbiturate that is effective as a sedative and hypnotic (but not as an anti-anxiety) agent and is usually given orally. It is prescribed more frequently for sleep induction than for sedation but, like similar agents, may lose its effectiveness by the second week of continued administration.

D003342 Corpus Striatum Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.

D013378 Substantia Nigra The black substance in the ventral midbrain or the nucleus of cells containing the black substance. These cells produce DOPAMINE, an important neurotransmitter in regulation of the sensorimotor system and mood. The dark colored MELANIN is a by-product of dopamine synthesis.
