[Background activity and responses of caudate nucleus neurons to a conditioned stimulus during polarization of the centrum medianum of the thalamus].
In chronic experiments on cats, the background and evoked activity of caudate nucleus neurones was studied, with the nucleus of thalamic median centre intact, but functionally eliminated by anodic polarization. During structure polarization, in 30 caudate nucleus cells an increase of mean frequency of action potentials was recorded, and in 22 cells--a decrease. The sign of conditioned reaction of caudate nucleus cells to a positive conditioned stimulus remained stable when the intact median centre nucleus was functionally eliminated. However, polarization of this structure changed the intensity and duration of individual components of the impulse response.
