[Spontaneous activity level and spike responses of cortical neurons to local supply of amino acids for dendrites and soma].
In guinea-pig parietal cortex slices, it was shown that neuronal spontaneous activity depended on dendro-somatic propagation of excitations evoked in dendrites. The functional dendritic properties are essentially non-uniform in the population of cortical neurons. Spike responses to direct soma activations are quite stable among neurons with various levels of spontaneous activity.
