title: [The spatial synchronization of the potentials in the background and evoked ECoG of a neuronally isolated strip of rabbit cortex].
abstract: Conditions of formation of potentials' spatial synchronization in the neuronally isolated cortical slab were studied in anaesthetized rabbits in acute experiments. Cortical potentials in all recording points of the slab were similar to each other. Seizure potentials induced by electrical stimulation spread over the slab and became synchronous in all points of recording. The neuronal division of the slab in two parts did not lead to a disturbance of initial synchronization of the background potentials in the isolated parts of the slab, while seizure potentials after electrical stimulation spread only over one part of the slab. These results suggest that the spatial synchronization of the EEG activity is a result of activity physically spreading from subcortical structures.
