[The characteristics of the spontaneous activity of single neurons in the human ventrolateral thalamus during changes in the functional state of the brain].
In the thalamic ventro-lateral nucleus of parkinsonian patients, two main types of convergent cells were shown to exist: 1) units with irregular discharges (A-cells, 74%) and 2) units with bursts of unstable rhythmic discharges (B-cells, 26%). The functional brain changes were accompanied by modifications of A-cells activity into the transient rhythmic burst-like pattern, characterized by two different types of intrinsic structure burst discharges being in some cases similar to the structure of B-cells. A correlation between activities of these units and the type of parkinsonian pathology was revealed.
