title: [Spinal, thalamic and cortical levels of splanchno-splanchnic interactions].
abstract: Using the occlusion method, we have shown splanchno splanchnic interactions on spinal, thalamic and cortical cells in cat. 1. At the first level, splanchno splanchnic interactions concern only the cells located in the Rexed V layer. The splanchnic fibres involved are small sized ones (Agammadelta, B and C types). 2. At the second level, splanchno splanchnic interactions have been observed in the VPL nucleus. The latencies of responses suggest that only large fibres are concerned. 3. At the third level, cortical cells of SI and SII areas have been studied. Splanchno splanchnic interactions have been elicited by different afferent splanchnic fibres (medullated and non medullated ones).
