[Changes in the impulse activity of neurons of the human thalamic ventrolateral nucleus during voluntary movement]. / Izmeneniia impul'snoi aktivnosti neironov ventrolateral'nogo iadra talamusa mozga cheloveka pri realizatsii proizvol'nogo dvizheniia.

Functional differences were revealed in evoked activity of two types (A and B) of units of the human thalamic ventro-lateral nucleus (VL). Collective activities of these polyfunctional neurons were selectively related to triggering and execution phases of movement. Common character of dynamics of the responses seems to be due to similar polyfunctional nature as well as to the functional role of these two complementary elements in the motor signal transmission. The collective activities reflect in the VL the integrative processes related to processing and programming of generalised parameters of motor signals, but unrelated to performance of a concrete motor act.

[Synthetic tripeptide miniluliberin and its biological activity]. / Sinteticheskii tripeptid miniliuliberin i ego biologicheskaia aktivnost'.

The effects of the synthetic decapeptide LH-RH and tripeptide mini LH-RH on LH and FSH secretion were compared. Experiments on ovariectomized female rats receiving estradiol benzoate and progesterone showed that i. v. administration of mini LH-RH produced a stimulating effect on the release of gonadotrophins from the hypophysis. The effects of mini LH-RH were incomparable to those of LH-RH.
