[Changes in the phasic evoked activity of cortical neurons following iontophoretic application of glutamate, GABA and atropine].
L-glutamic acid, GABA and atropine were applied ionophoretically from a microelectrode to single neurons in the somatosensory cortex of awake rabbits. The influence of the substances varied for the separate neuron response phases and depended on changes in electric stimulation parameters. A conclusion is made on the chemical specificity of separate phases of the neuronal responses and the neurochemical nature of the changes in the receptive fields of central neurons.
