[Spike activity of neurons of the medial thalamus of the rat during urethane anesthesia, wakefulness and immobilization stress].
A statistical analysis was carried out of unit activity in the medial thalamus (MT) of rats in states of urethane anaesthesia, quiet unrestrained wakefulness and immobilization stress. Discharge activity of MT neurones in these states significantly differed by parameters characterizing both single cells (mean frequency, standard deviation, variation coefficient) and their populations (intragroup variability of parameters, homogeneity of population as to the activity of its cells components, the extent of connections between them). The revealed differences are interpreted as a reflection of the properties of central interneuronal integration created in accordance with real needs of the organism for providing for its adaptive activity.
