Abstract
Cells of the medullary raphe nuclei were characterized as sympathoinhibitory (SI), sympathoexcitatory (SE) or serotonergic (5-HT). When muscular contraction (MC) was evoked by stimulation of the L7 and S1 ventral roots, putative SI cells were inhibited while putative SE cells were excited. 5-HT cells were unaffected by MC. These data are discussed in relation to integration of somatosensory and cardiovascular reflexes.
摘要
延髓中缝核的细胞被分为交感抑制性（SI）、交感兴奋性（SE）或5-羟色胺能（5-HT）细胞。当通过刺激腰7和骶1腹根诱发肌肉收缩（MC）时，假定的SI细胞受到抑制，而假定的SE细胞则被兴奋。5-HT细胞不受MC影响。结合躯体感觉和心血管反射的整合对这些数据进行了讨论。
