Amplitude of somatosensory cortical evoked potentials is correlated with spontaneous activity of spinal neurons in the cat E. Manjarrez, G. Rojas-Piloni, L. Martinez, D. Vazquez, D. Velez, I. Mendez, A. Flores Neuroscience Letters 323(2002):187-190 Introduction • Negative cord dorsum potential (CDP) • Monosynaptic reflexes and CDPs • Cortical neurons and dorsal horn spinal neurons Question • Correlation between spontaneous negative CDPs and somatosensory cortical evoked potential Method • • Adult cats Recording site: 1. Layer 3 to 6 of somatosensory cortex(S1) (glass micropipette) 2. L6 dorsal horn surface of lumbo-sacral spinal segment (silver ball electrode) • Stimulating site: – Electrical: Sural(SU) and superficial peroneus(SP) – Mechanical: hindpaw Result • High positive correlation between amplitude fluctuations of spontaneous negative CDPs and fluctuations of the cortical evoked potential
