在大鼠束旁核(PFN)记录到92个单位的单单位活动。刺激电极放置在三叉神经的中缝背段(DR)和脊束(SPV)。刺激DR或SPV均可引起PFN单位放电频率的显著变化。一些单位以短潜伏期驱动的活动回应。检测到输入的非驱动收敛。这些发现支持这样一种观点，即PFN可能是镇痛和痛觉感受的调制部位。
Single unit activity was recorded in 92 units in the parafascicular nucleus (PFN) of the rat. Stimulation electrodes were placed in the dorsal raphe (DR) and spinal tract of the trigeminal nerve (SpV). Stimulation of either the DR or SpV evoked significant changes in firing rates of PFN units. Some units responded with short latency driven activity. Drivenannd non-driven convergence of input was detected. These findings support the concept that the PFN may be a site of modulation of analgesia and pain appreciation.
