Abstract

Stimulation of hairy skin afferent fibers and/or direct depolarizing current injection initiates persistent changes in membrane potential (slow potentials), lasting up to 1 min or longer, in some deep dorsal horn neurons. Intracellular staining with horseradish peroxidase shows that these cells are interneurons, suggesting that slow potentials modulate moment-to-moment impulse transmission in local spinal circuits.

摘要

刺激有毛皮肤传入纤维和/或直接注入去极化电流，会在一些脊髓背角深层神经元中引发膜电位的持续性变化（慢电位），这种变化可持续长达1分钟或更长时间。用辣根过氧化物酶进行细胞内染色显示，这些细胞是中间神经元，这表明慢电位可调节局部脊髓回路中瞬间的冲动传递。
