Background and evoked activities of the caudate neurons were recorded extracellularly in acute experiments on cats. Different forms of potentials were observed in background and evoked activity. They could be divided into three types: (a) simple full size action potentials; (b) prepotentials characterized by smaller amplitudes and slower decrement; (c)(More)
Background activity recorded extracellularly from the caudate nucleus neurons was analyzed in immobilized cats. Experimental data processing included the plotting of average frequency curves, interspike interval histograms, intensity functions, correlograms and association histograms. The frequency of the background activity in different caudate neurons(More)
Extracellular recording from the caudate nucleus neurons were performed in experiments on immobilized cats during electrical stimulation of different parts of the same nucleus. Latencies varied from 3.5 to 40 msec. Most neurons could be excited by stimulation of the most rostral part of the caudate nucleus head. In most cases responses were independent of(More)
Unitary responses of the caudate nucleus to stimulation of various parts of it were investigated by extracellular recording. Latent periods of response discharges varied from 3.5 to 40 msec. Most neurons were excited by stimulation of the most rostral part of the head of the caudate nucleus. Irrespective of the site of stimulation, in most cases responses(More)
A study was made of brain bioelectric activity in 122 patients who developed organic lesions of the brain following their taking part in the elimination of the effects of Chernobyl disaster. A visual analysis was performed as was an assessment of the electroencephalogrammes (EEG) obtained, as recommended by E. A. Zhirmunskaia. Disorganization of(More)
Extracellular recording from the caudate nucleus neurons was performed in experiments on immobilized cats during paired stimulation of anterior sigmoideus and middle suprasylvius gyri. The findings indicate that the two cortical areas influence these neurons, the motor cortex having a greater influence on caudate neurons than the association cortex. The(More)
