Postsynaptic potentials (psps) produced by electrical stimulation of 4 forelimb nerves were recorded intracellularly from neurons in the primary somatosensory cortex of sodium pentobarbital anesthetized cats. Convergent inputs were found from nerves subserving different modalities and different regions of the forelimb. Psps from separate afferent sources usually did not sum linearly but rather interacted with one another. These interactions could have occurred at the cortical level or earlier in the ascending pathways and are interpreted with regards to the control of somatosensory responsiveness by multiple converging inputs.
在戊巴比妥钠麻醉的猫的初级体感皮层中，通过细胞内记录法记录了电刺激4条前肢神经所产生的突触后电位（PSP）。发现来自支配前肢不同感觉模式和不同区域的神经的汇聚输入。来自不同传入源的PSP通常不会线性叠加，而是相互作用。这些相互作用可能发生在皮层水平或上行通路的更早阶段，并根据多个汇聚输入对体感反应性的控制进行解释。
