Controlled temperature microstimulation of the frog semicircular canal (heating of 2 sec duration, peak amplitude from 0.5 to 5.0 degrees C above the temperature level of the labyrinth, 17-19 degrees C) may be considered as an analogue of angular acceleration in the plane of the canal. Combined temperature microstimulation of some canals may be considered as a physical model of complicated space rotations. Responses of the frog vestibular nuclei's neurons (n = 278) to temperature microstimulation showed that 80% of them had inputs from 1-2 canals and only 20% of neurons--from 3-6 canals. 201 neurons (72.3%) had ipsilateral inputs only; 14 neurons (5%)--contralateral ones only; 63 neurons (22.7%) had both inputs. The most effective excitatory inputs were ipsilateral horizontal, ipsilateral posterior and contralateral posterior canals; the least effective were contralateral horizontal and contralateral anterior canals. Latent canal inputs (excitatory as well as inhibitory) seem to exist as revealed in combination with the effective inputs.
对青蛙半规管进行控温微刺激（持续加热2秒，峰值幅度比迷路温度水平高0.5至5.0摄氏度，迷路温度为17 - 19摄氏度）可被视为半规管平面内角加速度的一种模拟。对一些半规管进行联合温度微刺激可被视为复杂空间旋转的物理模型。青蛙前庭核神经元（n = 278）对温度微刺激的反应表明，其中80%的神经元接收来自1 - 2个半规管的输入，只有20%的神经元接收来自3 - 6个半规管的输入。201个神经元（72.3%）仅具有同侧输入；14个神经元（5%）仅具有对侧输入；63个神经元（22.7%）同时具有双侧输入。最有效的兴奋性输入来自同侧水平半规管、同侧后半规管和对侧后半规管；最无效的是对侧水平半规管和对侧前半规管。与有效输入相结合显示，似乎存在潜在的半规管输入（包括兴奋性和抑制性）。
