  • Title: [Reactions of the neurons of the parietal association cortex in the cat that send axons into the pyramidal tract to peripheral stimuli].
    Author: Koreniuk II, Usachenko NM.
    Journal: Neirofiziologiia; 1988; 20(3):310-8. PubMed ID: 3173576.
    Abstract:
    Experiments were performed on cats anaesthetized with nembutal and immobilized with myorelaxin. Excitatory responses to somatic, light and auditory stimulation were recorded in 73.8, 57.7 and 65.4% of pyramidal tract (PT) neurons, respectively, whereas inhibitory responses--in 26.2, 42.3 and 34.6% of PT neurons. Among 64 PT neurons studied, trisensory cells accounted for 64.0%, bisensory--for 26.6%, monosensory--for 9.4%. The broad convergence of different-modality signals on PT neurons favoured their integration.
