多单位分析显示，NTS（孤束核）的吻侧区域含有对家兔舌吻侧味觉刺激有反应的细胞。使用代表性刺激的4种基本类型的味道，最大的发病率和幅度的反应，发现氯化钠，其次是盐酸，蔗糖和QHCl [奎宁盐酸盐]。对促味剂反应的时间模式的进一步分析揭示了刺激在潜伏期和时间过程中的差异。主成分分析表明，时间过程中，除了响应的幅度，可以有助于神经分化的tastants。信息也来自这些基本类型的促味剂的神经强度函数。对糖精钠的额外观察揭示了最小的神经元响应，尽管有报道的证据表明兔子对这种促味剂的行为偏好。
Multiunit analysis revealed a rostral region of NTS [nucleus tractus solitarius] containing cells responsive to taste stimulation of rostral tongue in rabbits. Using representative stimuli for the 4 bsic types of taste, maximal incidence and magnitude of response was found to NaCl, followed by HCl, sucrose and QHCl [quinine hydrochloride]. Further analysis of temporal patterns of response to the tastants revealed differences among stimuli in latency and time course. A principal components analysis indicated that time course, apart from magnitude of response, could contribute to neural differentiation of tastants. Information was also derived on neural intensity functions for these basic types of tastants. Additional observations with sodium saccharin revealed minimal neuronal responsivity despite reported evidence of behavioral preference for this tastant by rabbits.
